Soft Grade TPSIV

Updated: 2026-08-06

Overview

Soft Grade TPSiV is a high-performance thermoplastic elastomer that combines silicone's flexibility with the processing advantages of thermoplastics. This material is particularly valued in industries requiring both durability and soft touch properties. It bridges the gap between conventional rubber and rigid plastics, offering designers new possibilities in product development. The material is created through dynamic vulcanization, a process that disperses crosslinked silicone rubber within a thermoplastic matrix. This unique structure gives TPSiV its characteristic properties while maintaining the recyclability of thermoplastics. Major manufacturers have developed various grades to meet specific industry requirements.

Physical and Chemical Properties

Soft Grade TPSiV typically exhibits a Shore A hardness range of 30-70, making it significantly softer than many engineering plastics while maintaining good mechanical strength. The material maintains its elasticity across a wide temperature range (-50°C to +150°C), outperforming many conventional elastomers. Chemically, TPSiV shows excellent resistance to oils, fuels, and many polar solvents. Its silicone content provides inherent UV stability and weatherability. The material's low compression set (typically <30%) ensures long-term performance in sealing applications. Electrical properties include good dielectric strength and volume resistivity.

Main Applications

In the automotive sector, Soft Grade TPSiV is widely used for seals, gaskets, and vibration dampeners due to its temperature resistance and durability. The material's ability to maintain flexibility in cold climates makes it ideal for exterior components. The medical industry utilizes TPSiV for tubing, seals, and soft-touch components where biocompatibility is required. Consumer electronics manufacturers value it for buttons, grips, and protective cases that combine soft feel with structural integrity. Emerging applications include wearable devices and soft robotics components.

Safety and Storage

While generally safe to handle, processing Soft Grade TPSiV at elevated temperatures requires standard thermal protection measures. Adequate ventilation should be maintained when heating the material above its melting point to prevent exposure to potential decomposition products. For storage, the material should be kept in its original packaging in a dry environment at room temperature. Long-term exposure to high humidity should be avoided. Shelf life typically exceeds two years when stored properly. Recycled material should be clearly labeled and stored separately to prevent contamination of virgin material.

B2B Procurement Guide

When sourcing Soft Grade TPSiV, clearly specify required properties such as hardness (Shore A), tensile strength, elongation at break, and color consistency. For medical applications, verify FDA or USP Class VI compliance documentation. Consider ordering sample quantities for material testing before large purchases. Lead times can vary significantly (typically 4-8 weeks), so plan procurement accordingly. For custom formulations, minimum order quantities often apply. Establish quality control protocols for incoming material inspection, particularly for critical applications.
