Si-TPV 3100-55A Exceptional Aesthetics thermoplastic silicone-based elastomers
Description
Si-TPV is a dynamic vulcanizated thermoplastic Silicone-based elastomers which made by a special compatible technology , it helps silicone rubber dispersed in TPU evenly as a 2~3 micron droplets under microscope . This unique material provides a good combination of properties and benefits from thermoplastics and fully cross-linked silicone rubber. Suits for wearable device surface, Phone bumper ,Electronic devices accessories ( earbuds ,eg ), overmolding , artificial leather, Automotive, high-end TPE, TPU industries ….
Remark
The blue part is the flow phase TPU, which provides excellent mechanical properties.
The green part is silicone rubber particles provides silky skin-friendly touch, high and low-temperature resistance, weather resistance, stain resistance, etc.
The black part is a special compatible material, which improves the compatibility of TPU and silicone rubber, combines the excellent properties of the two, and overcomes the shortcomings of a single material.
