SILIKE outlines ways to improve polymer wear resistance

SILIKE says polymer wear resistance can be improved through resin selection, reinforcement, processing control and functional additives, depending on the base material and wear mechanism. The Chengdu company also points to silicone-based additives and anti-abrasion masterbatches for engineering plastics and footwear compounds.

Why it matters: - Polymer wear can shorten the life of gears, bushings, outsoles and other parts exposed to friction, sliding or abrasive contact. - Better wear resistance can improve component reliability without forcing tradeoffs in mechanical strength, processing stability or cost. - The choice of additive or formulation matters because lower friction does not always mean lower wear loss.

What happened: - SILIKE published a technical overview on how polymer wear resistance can be improved in engineering plastics and footwear compounds. - The article focuses on POM, PA6, PA66, EVA, TPU, TPR/TR, PVC and rubber systems. - SILIKE highlights silicone-based additives, anti-abrasion masterbatches and comparative test data for selected formulations. - The company also provides a website link for additional product information: the company's website.

The details: - Polymer wear is described as progressive surface damage or material loss caused by mechanical contact and relative movement. - Wear behavior depends on the full tribological system, including the polymer, counterface, load, sliding speed, temperature and environment. - The article identifies three common wear mechanisms: abrasive wear, adhesive wear and fatigue wear. - Abrasive wear occurs when hard particles or rough surfaces scratch, cut or repeatedly deform the polymer. - Adhesive wear occurs when local surface interactions cause material transfer, tearing or progressive damage during sliding. - Fatigue wear results from repeated loading that can lead to cracking, delamination and material loss. - Multiple wear mechanisms can occur at the same time. - Common improvement strategies include base polymer optimization, fillers and reinforcement, PTFE and solid lubricants, conventional lubricants, silicone-based additives and specialized anti-abrasion masterbatches. - Processing conditions such as mixing efficiency, filler dispersion, thermal history and molding parameters also affect final wear performance. - Silicone-based additives are presented as a way to modify surface interactions in compatible thermoplastic systems. - High-molecular-weight silicone additives can also influence lubrication and mold release. - SILIKE says improved processing or lower coefficient of friction alone should not be treated as proof of better abrasion resistance. - The article frames silicone-based wear modifiers as a PTFE-free option for manufacturers that need a compatible additive with measurable performance under specific operating conditions.

Between the lines: - The piece is as much a formulation guide as a product overview. - SILIKE is positioning silicone-based additives as one option among several, not as a universal replacement for PTFE or other lubricants. - The repeated emphasis on compatibility, dosage and validation signals that wear performance is highly application-specific. - The application data is useful, but the article makes clear that results can vary by formulation and test method.

What's next: - SILIKE says compounders should match additive selection to the base polymer, wear mechanism and processing conditions. - The company encourages comparative testing before finalizing a formulation. - SILIKE points users to wear-resistant options for POM, PA6 and PA66, plus footwear-focused products for EVA, TPU, TPR/TR, PVC and rubber. - The article says samples are available for evaluation.

The bottom line: - Improving polymer wear resistance is a formulation problem, not a single-additive fix. - SILIKE’s message is that the best result comes from matching the right resin, reinforcement and wear modifier to the end-use conditions.
