How to choose a transparent TPE manufacturer in Shenzhen

In the elastomer industry, TPE usually refers to composite functional materials obtained by modifying SEBS.

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

Transparent TPE material, due to high light transmittance, requires strict surface quality of the material product. It must not have any defects such as streaks, pores, whitening, halo, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, strict and even special requirements must be paid attention to regarding TPE raw materials, equipment, molds, and even product design.

TPE elastomer soft rubber has excellent comprehensive properties and is the most commonly used soft rubber material for secondary injection molding, overmolding, and two-color injection molding.

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

TPE is a classic aggregation-induced emission molecule, meaning it has no fluorescence in solution but strong fluorescence in solid state. Therefore, transparent TPE materials also have important applications in organic optoelectronics and other fields.

Styrene-based transparent TPE is widely used in the footwear industry, largely replacing rubber; at the same time, its use in industrial rubber products such as rubber cloth and rubber sheets is also expanding.

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

For secondary injection overmolding of nylon using an ordinary injection molding machine, it is recommended that before overmolding,

Transparent grade includes transparent and translucent series, each with various hardness levels; excellent transparency; smooth and soft surface; good anti-yellowing performance, tear resistance, good tensile strength; meets environmental requirements; suitable for various transparent series products.

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

First, preheat and bake the nylon part, because nylon has strong water absorption, and overmolding requires a high molding temperature; preheating before overmolding can remove moisture and facilitate rapid hot overmolding.
