2、 Application characteristics of thermoplastic rubber sebs-yh561
Yh-561 is a brand specially developed for low hardness elastomer products. Its outstanding feature is that it has high elastic modulus under high oil filling rate, and its elastic recovery is better than other brands. Under the same oil filling rate, the products produced by yh-561 have more dry surface and high hardness. Even under the strain of more than 600%, they also have excellent elastic recovery and moderate tensile strength, which can meet the requirements of various low hardness elastomers. They are mainly used for soft toys, vibration damping sheets, etc. It can also be used in the blending production of elastomer with high hardness.
 
3、 Typical application formula of thermoplastic rubber sebs-yh561:
1. The typical properties of products with 1 part yh-561 mixed with 4 parts 15# white oil and directly injected are as follows:
Tensile strength at break: 2.5MPa
Shore a hardness: 8
Elongation at break: 1000%
Breaking permanent deformation: < 20%
600% elastic recovery: > 98%
Compression set: < 5%
The product is transparent and the surface is free of oil.
