Lubricant G60 is generally a commercial grade or trade designation for a PVC processing lubricant, but the name alone does not identify one universally standardized chemical composition. In practice, I treat “G60” as a supplier-specific product code that must be confirmed through a technical data sheet, safety data sheet, and application evaluation. Depending on the manufacturer, it may be positioned for internal lubrication, external lubrication, or a balanced combination of both. For PVC buyers, the most important question is not only what G60 is called, but how its composition, dosage, melting behavior, and compatibility perform in the intended formulation.

In PVC compounding, a lubricant helps control friction between polymer particles, processing equipment, and the material surface. Internal lubricants primarily reduce friction within the PVC melt, while external lubricants help limit adhesion between the melt and metal surfaces such as barrels, screws, dies, and calibrators. A product described as G60 may support one of these functions or provide a controlled balance between them.
I recommend evaluating the product according to its measurable processing effect rather than relying on the grade name. Relevant observations include fusion behavior, melt torque, die release, surface appearance, plate-out tendency, and output stability. These effects can vary with PVC resin type, stabilizer system, filler loading, pigment package, processing temperature, and equipment design.
Internal lubrication can help reduce friction among PVC particles as the formulation changes from dry blend to a more homogeneous melt. This may influence fusion time, melt flow, torque development, and the balance between processing ease and final mechanical performance. Excessive internal lubrication can delay fusion, so I do not recommend selecting a dosage based only on the desired reduction in torque.
External lubrication is commonly associated with release from metal processing surfaces and improved control of die or calibrator contact. An appropriate external effect may help reduce sticking, surface drag, and deposits on equipment. However, too much external lubrication may interfere with fusion or create surface defects, particularly in profiles, pipes, sheets, and other products requiring a stable finish.
The best lubricant is often the one that provides a practical balance rather than the strongest single effect. For example, a formulation may require sufficient release during extrusion while still reaching uniform fusion within the available residence time. I therefore assess G60 together with the complete additive package instead of treating it as an isolated ingredient.
Lubricant G60 may be considered for rigid PVC extrusion, PVC profiles, pipes, sheets, fittings, and other molded or extruded products when the supplier confirms suitability. It can also be evaluated in formulations containing fillers, impact modifiers, stabilizers, pigments, and processing aids. The correct use depends on the actual grade specification and the customer’s equipment conditions.
Rigid PVC applications are particularly sensitive to fusion and release balance. Window profiles, construction profiles, and pipes may require consistent surface quality and dimensional stability, while filled compounds may need additional processing support because mineral fillers can change melt friction and torque. In injection molding, the buyer should also review cycle time, mold release, weld-line appearance, and part surface quality.
For each application, I recommend a controlled comparison against the current lubricant package. The comparison should use the same resin, stabilizer, filler, pigment, equipment settings, and production conditions wherever possible. This approach produces more useful information than comparing isolated laboratory values that may not represent the final formulation.
Because “G60” is not a universal chemical name, I ask suppliers to identify the material family behind the designation. Possible categories in PVC lubrication include metallic soaps, paraffin-based materials, fatty acid derivatives, ester lubricants, polyethylene waxes, oxidized waxes, and blended systems. These categories are not interchangeable, and each can influence fusion, release, gloss, plate-out, and downstream performance differently.
I also confirm whether the material is supplied as a powder, flake, bead, or other physical form. Particle size and bulk handling can affect dry-blend dispersion, feeding accuracy, dust management, and packaging efficiency. If the product is a blend, the supplier should explain the intended function of the blend without disclosing confidential formulation details.
A technical data sheet should provide enough information to support formulation screening and incoming quality control. The exact test methods matter because values from different methods are not always directly comparable. I normally review the following items before approving a G60 sample:

| Specification or characteristic | Why it matters | Buyer action |
|---|---|---|
| Physical form and color | Influences handling, appearance, and dry-blend consistency | Confirm against the production feeding system |
| Melting or softening range | Helps indicate behavior during PVC processing | Request the test method and typical range |
| Acid value, metal content, or other chemical indicators | May help identify functional behavior and batch consistency | Match values to the formulation requirement |
| Moisture and volatile content | Can affect storage, feeding, and processing stability | Define an incoming inspection limit |
| Recommended dosage | Provides a starting point for formulation trials | Validate through a controlled dosage study |
As a practical screening reference, PVC lubricant trials may be designed around a starting range such as 0.1–2.0 phr, meaning parts per hundred parts of resin, but this is not a universal specification for Lubricant G60. The actual dosage can be lower or higher depending on the product chemistry and total lubricant package. PVC processing commonly occurs in an approximate range of 160–210°C, but the correct temperature profile must follow the resin, equipment, and product design rather than this general reference.
I first request the current technical data sheet, safety data sheet, batch specification, country of origin, packaging details, and product revision date. The supplier should clearly state whether G60 is an internal lubricant, external lubricant, or multifunctional blend. If the chemical description is incomplete, I treat the product as a sample requiring technical validation rather than as a direct replacement.
I provide the supplier with the PVC application, resin K-value or resin grade where relevant, filler level, stabilizer type, processing method, and target output. This information helps the supplier recommend a realistic starting point. It also reduces the risk of selecting a lubricant that performs well in an unfilled formulation but causes fusion or surface problems in a heavily filled compound.
A suitable trial should measure both processing and product results. Useful observations include fusion time, torque profile, amperage, die pressure, output stability, surface appearance, deposits, dimensional consistency, and mechanical properties required by the application. I recommend recording the results at more than one dosage instead of testing only a single concentration.
For ongoing purchasing, I review batch-to-batch consistency, packaging integrity, storage recommendations, shelf-life information, and production capacity. A technically suitable material can still create problems if its physical form changes between shipments or if replenishment lead times are unpredictable. Buyers should also clarify whether the supplier can provide pre-shipment documentation and retain samples when required by their quality system.
One common mistake is assuming that every product called G60 has the same formulation. Commercial grade names are often supplier-specific, so a direct substitution should never be approved by name alone. Another mistake is judging performance only by surface gloss, because improved gloss does not necessarily indicate the correct fusion and lubrication balance.
Buyers also sometimes overlook the interaction between lubricant and stabilizer. A change in lubricant can alter processing torque, fusion development, color hold, and surface behavior even when the rest of the recipe remains unchanged. I recommend keeping a documented trial record and defining acceptance criteria before the sample is tested.
At Shitong, I approach Lubricant G60 sourcing as an application-matching process rather than a simple product-name inquiry. We can discuss whether the requirement is for internal lubrication, external lubrication, or a balanced PVC processing solution, then organize the relevant product information for technical review. Final suitability should be confirmed through the customer’s own formulation and production trial.
For B2B buyers, supplier support should include clear product documentation, representative samples, packaging and logistics information, and communication about recommended use conditions. Depending on the project, buyers may also request a sample quantity for laboratory screening and a commercial quotation based on the required packaging, order volume, destination, and delivery terms. I recommend confirming these details before treating a sample result as a production approval.
Lubricant G60 can be a useful PVC processing lubricant when its actual composition and intended function match the formulation and equipment requirements. The name alone is not enough to confirm equivalence, dosage, or performance because G60 may represent different supplier-specific products. I recommend requesting the technical and safety documentation, identifying the lubrication balance, and conducting a controlled trial using the complete PVC recipe.
If you are evaluating Lubricant G60 for PVC profiles, pipes, sheets, fittings, injection molding, or another application, share your resin system, filler level, processing method, target dosage, and purchasing requirements with Shitong. We can help organize the product evaluation, sample discussion, packaging details, and supply inquiry so that your team can make a more informed sourcing decision.
