Where is the best TPE for auto parts in Hubei

TPE elastomer soft rubber can be adjusted to the appropriate hardness based on the product's physical property requirements (hardness range Shore 25-90A),

Transparent TPE is used in stationery, sports equipment, etc., and has good UV resistance, chemical resistance, and is easy to color and process.

The wall thickness of TPE parts should be as uniform as possible to achieve the best molding cycle. Transitions between different wall thicknesses should be gradual to reduce fluid flow problems, such as air lines and bubbles.

and suitable physical properties (such as wear and scratch resistance, adhesion, melt index, etc.). It provides various possible material application plans for different products.

POM overmolding of POM. Although POM has a low melting point of only 180℃.

Transparent TPE is used in home appliance housings, handles, and grips, etc., exhibiting a very good hand feel, anti-slip and labor-saving, and easy to color and process. It also has a wide design space.

Since any impurities in the TPE material can affect the product's transparency, attention must be paid to sealing during storage, transportation, and feeding to ensure the TPE raw material is clean. Especially if the TPE raw material contains moisture, heating can cause the material to deteriorate, so it must be dried. During injection molding, a dry hopper must be used for feeding.

But due to its high crystallinity, forming a fusion layer on the overmolding surface requires higher energy. Meanwhile, due to POM's self-lubrication, it is not conducive to the rapid overmolding of TPE material on the surface of POM hard plastic parts.

The overmolding temperature is generally controlled at 30-50℃, but for some TPE grades with strong crystallinity,

Olefin-based transparent TPE has good weather resistance and ozone resistance, so it is called the fastest developing variety of TPE. It is mainly used as a major rubber material in fields such as automotive and home appliances.

To prevent contamination of TPE raw materials and the presence of old materials or impurities in the recesses of the screw and accessories, especially materials with poor thermal stability, all parts should be cleaned with screw cleaner before use and after shutdown to ensure no impurities adhere.

The mold temperature can be appropriately raised to 70℃, which is beneficial for adhesion and can also achieve a glossier overmolding surface.
