With the development of modern automobile industry and the continuous increase of automobile output, the demand for automobile interior fittings is also increasing rapidly. Among automotive interior trim products, thermoplastic elastic materials have the characteristics of comfortable touch, light weight, good weatherability and large design freedom, which make TPV/TPE a better choice for automotive interior trim products.
Advantages of TPV/TPE in Auto Parts
Large freedom of design
The processing method is flexible, and different processing methods such as injection molding, extrusion, calendering, blow molding, plastic suction, slush molding and the like can be used for processing. The appearance can be designed into matte, bright, transparent and translucent products with various appearances, thus improving the design freedom of product designers.
The product has excellent weather resistance and temperature resistance
The molecular structure of TPE/TPV material does not contain double bonds that are easy to age, and it can be endowed with excellent xenon lamp aging resistance and thermal oxygen aging resistance with high-quality weather-resistant additives. High temperature resistant TPE/TPV can be stably used at high temperature for a long time.
High processing efficiency
Complex products can be formed at one time, can be produced in batches by various forming methods, has high production efficiency, low cost and remarkable economic benefits.
Excellent physical properties
The product has excellent mechanical properties, good bending fatigue, wear resistance and rebound resilience. Soft to the touch, mild in texture, smooth and not sticky, stain-resistant, scrub-resistant, and not sticky with dust.
Taking the actual example of Tailifeng TPV as an example, the practical application of TPE/TPV materials in automobile interior fittings is simply listed:
1, low odor, odor level below 3.0, can reach 2.4 level stably;
2, low VOC, VOC release meets the requirement of 50mg/kg, and no benzene release can be detected;
3, smooth appearance, wear resistance, scratch resistance;
4. Good chemical solvent resistance;
5. High mechanical strength and good impact resistance;
6. Good weather resistance, high temperature resistance, heat aging resistance and light aging resistance;
7. Low compression permanent deformation;
8, the material can be recycled;
9. Environmental protection, meeting ROHS, REACH and other testing requirements.
