Environmental and Non-Toxic Properties of Thermoplastic Rubber TPE and Related Explanations
Time of issue:2025-08-09
Thermoplastic Elastomer (TPE) has been increasingly widely used in various industries in recent years. Various tools and products used in people's daily lives, such as toothbrushes, sex dolls, kitchenware, automotive interior parts, etc., may be made of TPE material. As a material that is getting more and more intimate contact with people, its environmental protection and non-toxic properties have naturally attracted widespread attention from the public.
### I. Concept and main components of TPE
TPE, whose full English name is Thermoplastic Elastomer, refers to thermoplastic elastomer in Chinese. It is a polymer alloy material made by blending styrene-based elastomers such as SBS and SEBS as the base materials with other components (such as PS, PP resins, white oil, filled calcium powder, compatibilizers, functional additives, etc.).
Therefore, it should be clarified to relevant experts that the basic components of TPE do not contain toxic toluene solvent.
### II. Environmental protection and non-toxic characteristics of TPE
Thermoplastic rubber TPE has been maturely applied in various industries for many years. There are different testing standards for different industries, such as the EU toy industry standard EN71-3, the NTFS testing standard for water dispenser equipment and components, the FDA and LFGB testing standards for food contact materials, REACH (SVHC), as well as testing for special substances such as 16P, NP, PAHs, BPA, etc. TPE materials fully meet the limits of relevant environmental protection regulations. Of course, TPE materials with different environmental protection requirements need to be adjusted in formula and controlled in the production process by material manufacturers.
### III. Environmental quality control in the processing of TPE products
1. Production environment:
For medical-grade and food-grade TPE materials, the working environment for raw material production and product processing is relatively strict. Generally, clean workshops are required for production and operation to ensure product quality.
2. Control the environmental performance of substances introduced in the processing process
If color matching is needed, the quality of colorants should be controlled according to the application of the product and specific environmental protection requirements; if painting or spraying is needed, attention should be paid to whether it can meet the environmental protection regulations of relevant products; if functional additives such as flame retardants and fragrances need to be added, customer requirements should be considered.
3. Suggestions for choosing TPE finished products
Although generally speaking, TPE materials are environmentally friendly, non-toxic and do not contain substances harmful to the human body. However, Superb (a brand name, can be retained as is or replaced with a general term like "we" if appropriate) suggests that when consumers choose TPE finished products, they should try to select well-known brands and suppliers with quality assurance. Some unscrupulous enterprises may compete for the market with low prices, but if the price is too low, the product quality will decline.
