China Cheap price Si-Tpv For Wearable Devices - Si-TPV 3420-90A silky touch dynamic vulcanizated thermoplastic silicone-based elastomers – Silike Detail:

DESCRIPTION

SILIKE Si-TPV® thermoplastic elastomer is a patented dynamic vulcanized thermoplastic silicone-based elastomer which made by a special compatible technology to help silicone rubber dispersed in TPU evenly as a 2~3 micron particles under microscope.Those unique materials combine the strength,toughness and abrasion resistance of any thermoplastic elastomer with desirable properties of silicone:softness,silky feel,UV light and chemicals resistance which can be recycled and reused in traditional manufacturing processes.

Si-TPV®3420-90A thermoplastic elastomer is a material with good abrasion and chemical resistance which can excellent bond to PC,ABS,TPU and similar polar substrates. It is a product developed for silky touch overmolding on wearable electronics, accessory cases for electronic devices, especially for phone cases.

APPLICATIONS

 

Solution for soft touch over molding on smart phones, portable electronic cases, ear buds, and other wearable electronic devices.

These process conditions may vary with individual equipment and processes.

  Secondary Processing

As a thermoplastic material, Si-TPV®  material can be secondary processed for ordinary products

 Injection Molding Pressure

The holding pressure largely depends on the geometry, thickness and gate location of the product. The holding pressure should be set to a low value at first, and then slowly increase until no related defects are seen in the injection molded product. Due to the elastic properties of the material, excessive holding pressure may cause serious deformation of the gate part of the product.

•  Back pressure

It is recommended that the back pressure when the screw is retracted should be 0.7-1.4Mpa, which will not only ensure the uniformity of melt melting, but also ensure that the material is not severely degraded by shear. The recommended screw speed of Si-TPV® is 100-150rpm to ensure the complete melting and plasticization of the material without material degradation caused by shear heating.

 

HANDLING PRECAUTIONS

A desiccant dehumidifying dryer is recommended for all drying.
