How to Choose Anhui Fireproof Overmolding TPE

TPE elastic soft rubber is used for secondary injection molding, overmolding and adhesion bonding.

The wall thickness of the TPE layer should be as uniform as possible to achieve the best molding cycle. The transition between different wall thicknesses should be gradual to reduce problems caused by fluid flow, such as gas marks and bubbles.

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

Fireproof Overmolding TPE

Because TPE material has good anti-slip properties and excellent elastic touch, it can enhance the tactile feel and grip of the product.

Overmolding POM onto POM. Although the melting point of POM is not high, only 180°C.

Transparent TPE materials exhibit different product properties in various applications. Thermoplastic elastomer, also known as TPE material, transparent TPE not only has the processing properties of thermoplastics but also the physical properties of vulcanized rubber. This is the combination of the advantages of plastics and rubber. Transparent TPE is widely used in people’s daily life and production.

Styrenic transparent TPE is widely used in the footwear industry, largely replacing rubber; at the same time, its applications in industrial rubber products such as rubber sheets and plates are also expanding.

Fireproof Overmolding TPE

However, due to its high crystallinity, forming a fusion layer on the overmolding surface requires high energy. At the same time, due to the self-lubrication of POM, it is not conducive to the rapid overmolding of TPE material on the surface of POM hard plastic parts.

TPE as raw material. TPE material manufacturers offer products that are environmentally friendly, non-toxic, have good elasticity, and smooth surface. In addition,

The thickness of the TPE/TPR overmolding layer. In most overmolding applications, a wall thickness range of 1.5-3.0mm will ensure good bonding effect. If the TPE layer is too thin, injection molding is difficult, bonding strength is low, and hand feel is poor. If the TPE layer is too thick, on one hand the cost is higher, on the other hand defects such as sink marks and bubbles are prone to occur.

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

Fireproof Overmolding TPE

The surface is not easy to attract dust, has good thermal conductivity, and excellent anti-soiling performance. Through skin safety and non-sensitization tests, it meets the properties that silicone cannot meet, making the appearance more high-end and refined, positioning TPE as the preferred high-end raw material in the industry.
