Environmental protection is the basic condition for people to value health. TPR material has been widely used in various industries in recent years. Various tools and products used in people's daily life, such as toothbrushes, kitchenware products, car interiors, etc., may be made of TPR material. TPR is a thermoplastic rubber. As a material in close contact with people, its environmental friendliness and non-toxicity are increasingly valued. There are different views on whether TPR material is toxic, non-toxic, environmentally friendly, or even suitable for high-end food.
Is TPR material toxic? Listen to the industry veteran explain in detail!
Is TPR material toxic? Listen to what the industry veteran says
So, thermoplastic rubber TPR material is non-toxic, listen to what the 7-year-old driver in the TPR industry says.
1. Concept and main components of TPR
TPR, English name is Thermo-Plastic Rubber. The Chinese meaning is thermoplastic rubber. It is a polymer alloy material, using styrene elastomers SBS, SEBS as base materials, adding PS, PP resin, white oil, calcium carbonate filler, compatibilizer, functional additives and other components. ). Therefore, the basic components of TPR do not contain toxic toluene solvent. Here, we should make a clarification to the relevant experts.
2. Environmental friendly and non-toxic characteristics of TPR material
TPR thermoplastic rubber has been used in various industries for many years. The testing standards for special substances vary: EN71-3 for the EU toy industry, NTFS testing standards for drinking water equipment industry, food contact materials, REACH (SVHC), FDA and LFGB testing standards, 16P, NP, PAHS, BPA testing, etc. TPR materials fully comply with the limits of relevant environmental laws and regulations. Of course, TPR materials with different environmental requirements require material manufacturers to adjust formulations and control production processes.
3. Environmental quality control of TPR product processing
Production environment: For medical grade and food grade
TPR material, the working environment requirements from raw material production to product processing are relatively strict. Generally, dust-free workshops are required for production and operation to ensure product quality.
To control the environmental performance of materials introduced during processing: if color matching is needed, the quality of colorants should be managed according to the application and specific environmental requirements of the product; if painting is needed, attention should be paid to whether it complies with the environmental regulations of related products, and functional additives such as flame retardants and fragrances should be considered according to customer requirements.
4. Suggestions for choosing TPR materials
Although TPR materials are generally harmless to the environment and non-toxic, and do not contain substances harmful to human health, the old driver suggests that consumers choose TPR products from well-known brand suppliers with quality assurance. Some inferior enterprises may compete with low prices in the market, but if the price is too low, product quality will decline.
Final summary: TPR is generally environmentally friendly and non-toxic. However, due to different industries and requirements, the environmental quality requirements for TPR materials will also vary. For food contact materials, skin contact materials, medical grade materials, etc., which are closely related to human health and safety, TPR raw material and product manufacturers will strictly control material quality to meet relevant testing standards and ensure the non-toxic safety of materials.
