How to choose TPR material manufacturers in Guangdong

TPE elastomer soft gel can be adjusted to the appropriate hardness (hardness range Shore 25-90A) according to the physical property requirements of the product,

The thickness of the 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 will be difficult, adhesion strength will be low, and the feel will be poor. If the TPE layer is too thick, on one hand the cost is higher, and on the other hand defects such as sink marks and bubbles are prone to occur.

Transparent TPE materials require high light transmittance, so the surface quality of the product must be strictly controlled. No defects such as streaks, pores, whitening, fogging, black spots, discoloration, or poor gloss are allowed. Therefore, during the entire injection molding process, strict and special requirements must be paid to the TPE raw materials, equipment, mold, and even product design.

And appropriate physical properties (such as wear and scratch resistance, adhesion, melt flow index, etc.). Various possible material application plans are provided for different products.

TPE is used in overmolding, with TPE soft gel as the outer coating layer,

The wall thickness of the TPE layer should be as uniform as possible to achieve the best molding cycle. Transitions between different wall thicknesses should be gradual to reduce flow-related problems such as flow marks and bubbles.

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

Common matching rigid materials are mainly plastics, but also metals and fabrics. TPE overmolding with fabric is mainly used in luggage products. Similar to metal overmolding, it is generally false overmolding. True overmolding is more common in two-shot injection molding and two-color injection molding, where the main material for TPE overmolding is plastic.

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

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.

Transparent TPE materials have different product properties when applied in different aspects. Thermoplastic elastomer, also known as TPE material, not only has the processing properties of thermoplastic plastics but also the physical properties of vulcanized rubber. This is the advantageous combination of plastic and rubber. Transparent TPE is widely used in people's daily life and production.

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