2021 High quality Si-TPV - TPO based Skin-friendly thermoplastic elastomer Si-TPV 2150-55A – Silike Detail:

Description

SILIKE Si-TPV® 2150-55A thermoplastic elastomer is a patented dynamic vulcanized thermoplastic silicone-based elastomer which made by a special compatible technology to help silicone rubber dispersed in TPO 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® 2150-55A can excellent bond to TPE and similar polar substrates like PP, PA, PE, PS, etc… It is a product developed for soft touch overmolding on wearable electronics, accessory cases for electronic devices, automotive, high-end TPE, TPE wire industries ……

 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.

Remark

1. Si-TPV elastomer products can be manufactured using standard thermoplastic manufacturing processes, including overmolding or co-molding with plastic substrates such as PP, PA.

2. The extremely silky feel of Si-TPV elastomer does not require additional processing or coating steps.

3. The process conditions may vary with individual equipment and processes.

4. A desiccant dehumidifying drying is recommended for all drying.
