How to Choose Transparent TPE Manufacturers in Guangdong

TPE material is used for overmolding and injection bonding, with TPE soft rubber as the outer covering layer,

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

Olefin-based transparent TPE has good weather resistance and ozone resistance, so it is known as the fastest-growing variety among TPEs, and it is mainly used as a rubber material in automotive, home appliances and other fields.

Common rigid materials used in combination are mainly plastics, as well as metals and fabrics. TPE injection bonding with fabric is mainly used in luggage products, and like metal overmolding, it is generally false overmolding.

PP overmolding is a plastic with very weak polarity, which is very close to the polarity of TPE based on SEBS substrate.

Transparent TPE is used in home appliance shells, handles, grips, etc., showing very good hand feel, anti-slip and labor-saving, and easy coloring and processing, with a wide design space.

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

Therefore, for overmolding PP, the most conventional TPE formula can be directly used without adding polarity modifiers.

For secondary injection overmolding of nylon using a standard injection molding machine, it is recommended before overmolding,

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

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

First, preheat and bake the nylon parts because nylon has strong water absorption, and overmolding requires high molding temperature; preheating before overmolding removes moisture, facilitating rapid overmolding while hot.
