Regarding toys, Wang Fu of the Han Dynasty said in his ‘Theory of Lurking. In his book, ‘The Book of Floating Extravagance’, Wang Fu of the Han Dynasty said, ‘Toys are the tools for playing with children’, that is to say, they are the things that amuse children to play with. The definition of toys is actually very broad, anything that children can play, see, hear and touch can be called a toy.
Toys are the medium through which children turn mental processes such as imagination and thinking into behaviour. Children's toys can develop motor skills, train perception, stimulate imagination, arouse curiosity, and provide material conditions for children's physical and mental development.
Excellent toys in addition to its basic qualities, but also need to meet the health requirements and safety requirements. Therefore, there are also high requirements in the selection of materials. Here we take the bouncy ball as an example and briefly analyse the different characteristics of different materials.
Generally speaking, most of the elastic balls for children on the market are made of rubber, which is a highly elastic polymer material with reversible deformation and elasticity at room temperature. Rubber molecular chain can be cross-linked, cross-linked rubber deformation by external forces, with the ability to quickly recover, and has good physical and mechanical properties and chemical stability.
However, rubber also has its own irresistible shortcomings, that is, rubber and its products in the processing, storage and use of the process, easy to internal and external factors of the combined effect of the physical and chemical properties of rubber and mechanical properties of the gradual deterioration of the final loss of the use of value, that is, the rubber is easy to aging, specific manifestations of cracking, sticky, hardening, softening, pulverisation, discolouration, mildew and so on. These phenomena, whether for adults or children are more unfavourable, and even for the environment is not good.
In fact, there is a more suitable material can be used in the elastic ball, that is, EVA foam material, the material is a new type of environmentally friendly plastic foam material.
EVA foam material has good cushioning, impact resistance, heat insulation, moisture resistance, chemical resistance and other advantages, and non-toxic, non-absorbent and many other advantages, so it is widely used in many industries, but its resilience, abrasion resistance, heat shrinkage and so on there is a lot of room for improvement. How to make its advantages more prominent and at the same time improve these shortcomings? Compared with traditional POE, OBC and other foam modifiers, Si-TPV Soft EVA Foam Modifier can better help EVA foam to complete the enhancement.
Si-TPV stands for Silicone Thermoplastic Vulcanizate, an innovative material that combines the elasticity of silicone rubber with the processability of thermoplastics. It is a Silicone For EVA Foaming…This unique combination offers many advantages, especially when used with Soft EVA Foam Modifier Solutions. Si-TPV is an excellent Flexible Soft Eva Foam Material Solutions when used as a Soft EVA Foam Modifier to give the material better resilience and improved compression set during the EVA foaming process. As wear and tear is unavoidable in daily use, improving the abrasion resistance of the foam material is also a very important concern. Si-TPV Soft EVA Foam Modifier can well improve the abrasion resistance and extend the service life of the toy. In addition, Si-TPV Soft EVA Foam Modifier can reduce heat shrinkage, help heterogeneous nucleation, and make the foam pores more uniform and dense.
Si-TPV Soft EVA Foam Modifier in EVA foam can make the colour saturation higher and the colour choices more abundant and diversified, on the one hand, it can enhance the children's observation, memory and concentration, stimulate their curiosity and desire to explore, and promote their understanding of the world around them and cognitive development. On the other hand, it also gives the toy designers more colour design Freedom. As a product mainly related to children's activities, the hygiene and safety of the product must be the top priority. As Si-TPV is 100% Sustainable Elastomeric Materials, Plasticiser-Free Thermoplastic Elastomer, Eco-Friendly Elastomeric Materials Compounds, it has passed the food contact standards of FDA and GB and other food contact standards, the skin is not allergic, so it is used in EVA foam toys will not cause burden and harm to the environment and human body.
From these advantages, I believe you can also see a direction of the application of this material, that is, bouncy balls.
In addition to bouncy balls, crawling mats are also a place where this material can be used to great effect. Crawling mats using Si-TPV as a foam additive are soft, elastic and not easily deformed, providing good support and protection for children whether they are crawling, running or jumping.
Of course, Si-TPV can also be used in other aspects of children's foam toys, such as Modifier For Foam Float Board, or as a foam modifier for ocean balls, blocks, castles, and all kinds of patchwork toys.
