How to enhance the anti-scratch of polypropylene material for automotive interiors?

As the automotive industry continues to evolve, manufacturers are looking for ways to improve the quality of their vehicles. the most important aspect of vehicle quality is the interior, which needs to be durable, resistant to scratches, and low VOC…

Polypropylene(PP) has been widely used in automotive interiors for its characteristics of high-cost performance, low density, excellent heat resistance, chemical corrosion resistance, easy molding processing, and recycling.

However, PP is easily scratched by sharp objects, and its surface can be easily damaged by abrasion. Additionally, PP is prone to UV degradation, which can further reduce its scratch resistance. the scratch and mar performance of these products typically doesn’t fulfill all customer expectations. And, the traditional anti-scratch agent contains a high amount of volatile organic compounds (VOCs). These VOCs can easily evaporate and be released into the air when applied to polypropylene (PP) surfaces. This can lead to an increase in the VOC content of the PP, which can be hazardous to human health.

How to improve scratch resistance while controlling the VOCs level of polypropylene material!? we would hate for you to miss out —-Scratch Resistant Polypropylene Solutions!!!

Enhancing the scratch resistance of polypropylene material involves a combination of material modifications, additives, and surface treatments. Here are some strategies PP manufacturers can consider:

1. Fillers and Reinforcements:

1) Add fillers like calcium carbonate or talc to improve hardness and scratch resistance.

2) Incorporate reinforcing materials like glass fibers to enhance the mechanical properties and scratch resistance of polypropylene.

2. Surface Treatments:

1) Apply coatings: Clear coatings, lacquers, or varnishes can provide a protective layer on the surface, improving scratch resistance.

2) Plasma or corona treatment: Modify the surface properties of the polypropylene to increase its resistance to scratching.

3. Additives:

1）Incorporate scratch-resistant additives: Additives such as nano clays, talc, silica, or glass fibers can reinforce the polypropylene matrix and improve scratch resistance.

2）Use impact modifiers: Impact-modified polypropylene (TPO) or blending with other polymers like ABS can enhance scratch resistance.

3) Consider slip agents: Slip additives like fatty amides or erucamide can reduce surface friction and make the material more resistant to scratching.

Whereas, for the automotive industry, among the many additives, SILIKE Silicone Masterbatch (Anti-scratch masterbatch) is considered one of the most effective ways！ Since SILIKE Silicone Masterbatch (Anti-scratch masterbatch) series product is pelletized formulation with ultra-high molecular weight siloxane polymer dispersed in polypropylene and other thermoplastic resins and has good compatibility with the plastic substrate. that provides superior scratch resistance for PP and TPO auto-body parts, and enhanced compatibility with the Polypropylene matrix — Resulting in lower phase segregation of the final surface, which means it stays on the surface of the final plastics without any migration or exudation, reducing fogging, VOCs (volatile organic compounds) which helps to improve air quality in the automotive(vehicle )interior from the source. This makes it an ideal solution for those looking to reduce emissions from their vehicles. and is easy to incorporate as they consist of solid pellets.

What is SILIKE Silicone Masterbatch (Anti-scratch masterbatch)?

SILIKE Silicone Masterbatch (Anti-scratch masterbatch) LYSI-306 provide anti-scratch solutions to various PP/Talc interior application, with dosage from 0.5% to 3% of LYSI-306, the scratch resistance of finished parts meets the standard of VW PV3952, GM GMW14688, Ford, etc. due to SILIKE Silicone Masterbatch (Anti-scratch masterbatch )LYSI-306 is a pelletized formulation with 50% ultra-high molecular weight siloxane polymer dispersed in Polypropylene (PP). It helps improve long-lasting anti-scratch properties of automotive interiors, by offering improvements in many aspects like Quality, Aging, Hand feel, Reduced dust buildup… etc
