Environmentally friendly waterproof bibs for children are now made of thermoplastic elastomer TPE and silica gel:
Thermo-plastic elastomer TPE, also known as thermoplastic rubber, English name Thermo-Plastic Rubber. It is transparent in appearance, solid in color, and has rubber characteristics. TPR is a thermoplastic material with vulcanized rubber characteristics. It has excellent resilience, soft touch, wear resistance and aging resistance. TPR is a blend modified elastomer alloy based on SBS and SEBS thermoplastic elastomer. Its physical properties and hardness (0~100A) can be realized by adjusting the types and proportions of components of SEBS and SBS blending system, so as to adapt to various industrial fields with different application requirements.
Characteristics of silica gel material: silica gel is a thermosetting elastomer with the advantages of safety and innocuity, insoluble in water and any solvent, nontoxic and tasteless, stable in chemical properties, not reacting with any substance except strong alkali and hydrofluoric acid, high in adsorption performance, good in thermal stability and stable in chemical properties, and was first widely used in adult articles and food products.
The price of silica gel is generally more than 30,000 yuan per ton, while the price of TPE is generally between 13,000 yuan and 30,000 yuan. TPE has more advantages in price, except for special TPE materials, such as halogen-free flame retardant, food grade, etc.
Silica gel has advantages over TPE in high temperature resistance. The temperature resistance of silica gel is generally between 200 and 300 degrees, while TPE is theoretically generally between 130 and 150 degrees, and then it will be aged and cracked.
Both have their own advantages, but TPE meets the requirements of silica gel in terms of processing performance, recyclability and cost price. With more and more types and applications of TPE, TPE is the preferred material to replace silica gel!
The bib is a necessary eating equipment for every child. Children will never dirty clothes when eating, and mothers will also be less worried about the trouble of washing greasy clothes. The most important thing is that the children of the church pay attention to hygiene habits. The children do not pay attention to eating, resulting in greasy debris falling onto the clothes, which is difficult to clean. Therefore, the baby bib was born. Selecting TPE raw materials or silica gel to produce baby bibs can meet the functions of the bibs.
The TPE waterproof bib material produced by Dongguan Dechuang Chemical Co., Ltd. has been mature and applied to the market. The TPE waterproof bib material has separate molding and secondary injection molding of rubber PP. Customers are welcome to call for consultation and negotiation!
