With the improvement of people’s consumption level, automobiles have gradually become a necessity for daily life and traveling. As an important part of the car body, the design workload of automotive interior parts accounts for more than 60% of the workload of automotive styling design, far more than the car’s shape, which is one of the most important parts of the car body.

Automotive interiors are not only an element but also a highlight, the production of interior parts should be safe and environmentally friendly but also to ensure its good decorative effect. For people who have a car, one of the biggest headaches is that with the use of the scene, temperature, time, and many other factors, a series of interior problems ensue:

1. Scratches on the interior caused by regular scrubbing of the car, affecting the performance of the interior as well as its aesthetics;

2. VOC gas release caused by long-high temperatures in summer;

3. Problems such as aging, precipitation, and stickiness occurring after a long period of use.

The emergence of various problems also makes consumers become more discerning, but to promote the automotive industry to enhance the performance of automotive interior thinking.  the most widely used materials in automotive interior and exterior applications are PP, talc-filled PP, talc-filled TPO, ABS, PC(polycarbonate)/ABS, and TPU (thermoplastic urethanes) among others. However, the scratch performance of talc-PP /TPO compounds has been of great focus. How can to improve scratch resistance while controlling the VOC level of talc-PP /TPO compounds? Automotive interior material scratch-resistant agents also came into being. Currently on the market commonly used scratch-resistant agents, such as amides, although with a small amount of additive, cheap and good scratch-resistant effect and so on, but in the precipitation, viscosity and VOC release and other aspects of the effect are not ideal.

SILIKE  scratch-resistant agents—Silicone Masterbatch (Anti-scratch masterbatch) is considered one of the most effective ways！ Since SILIKE Silicone Masterbatch (Anti-scratch masterbatch) series product is a 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, effectively avoids scratches due to external forces or cleaning, 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, ensure that the performance of the interior parts of the automotive interior and aesthetics. This makes it an ideal solution for those looking to reduce VOC emissions from their vehicles.

A Case Study on Scratch-Resistant Solutions for Automotive Interiors

Compared to conventional lower molecular weight Silicone / Siloxane additives, Amide, or other types of scratch additives, After adding a small amount of SILIKE Anti-Scratch Silicone Masterbatch LYSI-306C, the scratch resistance of the PP/TPO compounds for automotive interior parts is significantly improved, achieve long term scratch resistance, Under the pressure of 10N, the ΔL values less than 1.5, meeting anti-scratch test standards PV3952 and GMW 14688. And the mechanical properties of the parts are basically not significantly affected. This Scratch Resistant Agent SILIKE Anti-Scratch Silicone Masterbatch LYSI-306C has the advantages of odorless and low VOC release, which can avoid the release of toxic gases from automotive interior parts that are harmful to human health under high temperatures and sun exposure.

This scratch-resistant additive SILIKE Anti-Scratch Silicone Masterbatch LYSI-306C is widely used in all kinds of PP, TPO, TPE, TPV, PC, ABS, PC/ABS modified materials, automotive interiors, household appliance shells, and sheets, such as door panels, dashboards, center consoles, instrument panels, home appliance door panels, sealing strips.

Additionally, the Scratch-resistant agent is available in the market and within shorter lead times directly from  Chengdu Silike Technology Co., Ltd.
