Environmental protection is the basic condition for people to pay attention to health. In recent years, TPR materials have been widely used in all walks of life. A variety of tools used in People's Daily life, such as toothbrushes, kitchenware, car interiors, etc. Can be made of TPR material. TPR is a thermoplastic rubber. As a kind of material with more and more close contact with people, its environmental protection and non-toxic characteristics have naturally aroused widespread public concern. On whether the TPR soft rubber material is toxic, some people say that it is toxic, some people say that it is environmentally friendly, and even some people say that it reaches the level of food.

1.TPR concept and main components

TPR, the English full name is thermoplastic rubber. It means thermoplastic rubber in Chinese. It is a polymer alloy material made of styrene elastomer SBS and SEBS as the matrix material, adding other components (such as PS, PP resin, white oil, filled calcium powder, compatibilizer, functional additives, etc.). Therefore, the basic components of TPR do not contain toxic toluene solvents.

2.TPR soft rubber material is environmentally friendly and non-toxic.

TPR soft rubber (thermoplastic rubber) has been used for many years in various industries, and different industries have different testing standards, such as EN71-3 in the EU toy industry. Water machine equipment industry NTFS testing standards, food contact materials FDA, LFGB and other testing standards, REACH(SVHC), special substances such as 16P, NP, PAHs, BPA and other testing. TPR materials fully comply with relevant environmental laws and regulations. Of course, for TPR materials with different environmental requirements, material manufacturers need to adjust the formula and control the production process.

3.TPR product processing environmental quality control

Production environment: For medical grade and food grade TPR soft adhesive materials, the working environment of raw material production and product processing is relatively strict. Generally, a dust-free workshop is required for production operations to ensure product quality.

Control the environmental performance of the substances introduced in the processing process: if the color needs to be matched, the quality of the colorant should be grasped according to the application of the product and the specific environmental requirements; If you need to spray oil, pay attention to whether it can meet the environmental protection regulations of relevant products; If you need to add functional additives, such as flame retardants, flavors, etc. You should consider the customer's request.
