Multibase A Dow Corning Corporation TPSiV siloxane Elastomers

TPSiV  (TPE + siloxane) "Unique!"

With the product family TPSiV ™ are properties of silicone rubber, such as high temperature strength and low abrasion, with characteristics of conventional thermoplastics, such as mechanical strength and easy processability combined.

TPSiV ™ is synthesized in a dynamically designed vulcanization silicone rubber and an engineering thermoplastic. In the final product fully vented and cross-linked silicone rubber are domains in the continuous matrix of the thermoplastic dispersed. Silicone rubber is the soft, the respective thermoplastic hard component of the TPE. Since mainly the continuous matrix determines the processing characteristics of the entire material TPSiV ™ is to process despite the high proportion of elastomer with conventional extruders and injection molding machines.

This unique material development has the following properties:
High and low temperature resistance
Next hardness without the use of plasticizers
Conventional thermoplastic processability
Very good 2K connection to all common thermoplastics (except POM)
High chemical resistance
Elastomeric behavior
Recyclable
High abrasion resistance
Pleasant silky feel
Complete painting and printability
Excellent weldability

.

These proprietary compounds feature crosslinked silicone rubber dispersed within a matrix of TPU or other thermoplastic resin. As a class, TPSiV compounds share a significant set of properties. The silicone rubber contributes resistance to chemicals, UV, and heat; while the TPU phase provides abrasion resistance, bonding, color versatility, and processing simplicity. Because resilience is achieved without using plasticizers, these materials provide luxurious, silky feel and minimize issues associated with volatile emissions or migration.

TPSiV™ 3040-55A / 60A / 65A / 70A / 85A Thermoplastic polyurethane.combine the benefits of excellent abrasion resistance from the polyurethane as well as the lower coefficient of friction and improved temperature properties from the silicone rubber.Plasticizer free, these grades are designed for good flow characteristics and a unique “silky” feel. They are used in injection molding applications, specifically overmolding and co-molding on PC and ABS. They exhibit good abrasion resistance, and good retention of properties in harsh environments. They are commonly used in communication devices, computers, and electronic devices.
