Foaming Thermal Rubber -lightweight Thermoplastic Rubber

Foaming Thermal Rubber -lightweight Thermoplastic Rubber

Product Details

FTR (Foaming thermalplastic rubber)- ultra - light injection rubber 

FTR (Foaming thermalplastic rubber) is a new type of elastomeric composite. It is a lightweight thermoplastic rubber. The product has excellent performance and can be molded by injection molding.

FTR has characteristic of low density, high elastic, comfortable, feel good, the appearance color is even, no flow pattern, the surface matte, the fog surface effect is good. You can achieve high quality and smooth appearance without spraying. And it can be recycled 100%. It is a new kind of eco-friendly sole material.

Features of FTR:

1. Excellent matte surface effect (no spraying)

2. Excellent slip-resistance.

3. Excellent wear resistance: DIN is less than 200mm3.

4. Excellent winding resistance performance: - 20 folding more than 60000 times

5. Super light specific density:  0.65-0.8g/cm3.

6. Has strong rubber texture, high elasticity and comfortable.

7. The processing performance is excellent, it can be molding by the disk injection molding machine.

8. It is completely eco-friendly and can be recyclable and cyclic utilization.

Performance comparison and discrimination.

6. TR bottom:

The sole of TR is shiny. It is harder than the regular TPR sole. The injection hole of TR is more than TPR, and the injection hole is very special.


Weight: RUBBER (RUBBER) heaviest, PU, EVA is the lightest, material: PU is expensive, EVA, TPR is moderate, PVC is the cheapest,

Process: TPR is made to be a molding, and PVC to be processed.

Price: TPR is the cheapest, PU=TPR * 2 times, MD=TPR * 3 times, MD air cushion TPR * 4 times, PU air cushion TPR * 4-6 times.


PVC has a wide range of application, can be like a single bottom of the United States, or it can be shaped like a TPR. The PVC can also be molded into a single bottom (within 4mm), and the injection molding comes out with a bottom flower, without grinding edges.

The TPR base is usually molded by mould-shaped injection molding. Since TPR is to be foamed, there must be a considerable amount of space (thickness) to produce bubbles and to achieve foaming effect, so the sole thickness of the sole will be used when the sole thickness is above 5mm. Of course, it can also be injected into a single bottom, but there is no foaming space; And TPR materials are more expensive, so PVC is usually used. Some people use TPR to make a pair of sole size, and then make a cut; But TPR is foaming, it is not good to wear edge, although the unit price is cheaper than the United States, but the property is poor, it is not practical.

Both TPR and PVC injection moulds can be colored on raw materials, and can be painted and painted.
