Company Profile

 TPE (Thermoplastic Elastomer) is a kind of polymer material that combines the elasticity of rubber and the plasticity of plastic. It has the advantages of being environmentally friendly, resistant to aging, and easy to process. It is widely used in the fields of automobiles, electronics, and medical care.

Basic Characteristics of TPE Materials

Combination of Elasticity and Plasticity: TPE exhibits rubber-like elasticity at room temperature and can be molded into shape at high temperatures without the need for vulcanization processing.

Microstructure: Composed of plastic segments (hard segments) and rubber segments (soft segments), the hard segments form physical cross-linking points, while the soft segments provide elasticity.

Environmental Friendliness: Recyclable, in line with green material standards, non-toxic and odorless.

Core Advantages

High processing efficiency: Compared to traditional rubber, the processing flow is shortened by 25%, and energy consumption is reduced by 25% - 40%. 

Performance can be adjusted: By adjusting the ratio of hard segments to soft segments, hardness (10A - 95A), tensile strength (3 - 10 MPa), and other parameters can be customized. 

Strong weather resistance: Resistant to ultraviolet rays and chemical corrosion, suitable for outdoor and industrial environments.

FAQ

Q:What's the difference between TPE compounding and TPU processing?
A:TPE compounding: Blends TPE with additives/fillers via mixing/extrusion to customize properties (e.g., hardness, elasticity). Focuses on formulating unique material blends. TPU processing: Shapes TPU raw materials (with inherent high strength/wear resistance) into products (e.g., belts, soles) via injection molding/extrusion. Focuses on controlling parameters (temp, pressure) to form products.

Q:How to ensure quality of TPR for toys?
A:Raw material check: Verify TPR composition (no harmful heavy metals/plasticizers) and test basic properties (melt flow rate). Production monitoring: Control mixing/extrusion temp, screw speed to ensure uniform ingredient dispersion. Final product tests: Check mechanical properties (tensile strength, tear resistance), safety (harmful substance release), and appearance (no bubbles/impurities).

Q:What are key traits of TPV automotive sealing strip production?
A:Process: Select TPV (with additives for weather resistance), extrude (control temp ~180-220°C), then cool, cut, and surface - treat (or embed metal strips). Advantages: TPV's thermoplastic nature enables efficient continuous extrusion. Its aging resistance and compression set performance suit long - term automotive dynamic sealing needs.
