TPR Fuel Injection Toy Materials: Product Description: TPR doll toy material. This product is made of TPR material. It has the characteristics of high strength, high resilience of rubber, injection molding, environmental protection, excellent coloring, soft touch, weather resistance and superior processing performance. Pellets are divided into transparent color and white color, the common hardness range is 20-85 A, and the specific gravity is 0.9-1.7. It is the best choice for eraser dolls. TPR doll toy features: 1, the material color is transparent or white, can match colors. 2, environmental protection, can pass the toy series of environmental testing. 3, the forming period is short, the production efficiency is greatly improved, and energy can be effectively saved by recycling. 4, stable quality, easy molding, easy coloring spraying. 5. The materials have high cost performance and can be customized according to requirements. TPR Injection Toy Material Forming Precautions: 1.TPR material has moderate fluidity, convenient molding and processing, injection molding temperature: 170~190℃, and is not prone to appearance problems such as shrinkage and burrs. 2. TPR doll products with SBS as the main substrate should strictly control the process. It is better to mix the materials horizontally instead of using a high-speed mixing barrel, and the time should not be too long. 3. Generally speaking, the processing temperature should be controlled as low as possible. 180 degrees in the shearing section and 160 degrees in the later sections are sufficient. Generally speaking, SBS over 200 degrees is easy to age and its odor will increase a lot. 4. The TPR pellets made should be cooled as soon as possible to volatilize the odor and ensure that there is not much heat during packaging.
