High Tensile & Tear Resistance: How Powerful Is Custom TPR Encapsulation Material?

2026-09-16 0 Leave me a message

Durability is a key indicator for qualified TPR encapsulation materials. Conventional flexible encapsulation materials commonly suffer from low tensile performance, poor tear resistance and structural instability during frequent bending and friction. This article presents the high-tensile and high-tear custom TPR encapsulation materials from Zhongsu Wang, covering core performance data, customizable features, processing technology, certifications and practical application values for industrial manufacturers.

Core Performance Data: High Tensile & Tear Resistance Advantage

Zhongsu Wang custom TPR encapsulation materials adopt optimized formulas and German Leistritz co-rotating twin-screw production lines with a metering accuracy of ±0.3%, ensuring stable and consistent mechanical properties. Verified by standardized industrial tests, the material delivers reliable physical performance:

Tensile Strength:

Max 9.2MPa, resistant to stretching and extrusion cracking during assembly and daily use.

Tear Strength:

Max 82KN/m, effectively preventing edge cracking and local damage under repeated twisting and high-friction conditions.

Elongation at Break:

Up to 574%, providing excellent toughness and deformation recovery to extend product service life.

All performance data comply with international industrial standards, maintaining stable physical properties in regular working environments.

Customizable Full-Spec Formula to Match Diverse Industrial Scenarios

Zhongsu Wang TPR encapsulation materials support customized hardness ranging from 20A to 100A Shore. Specific gravity and melt index can be adjusted to fit different product structures and injection molding processes.

Based on stable mechanical performance, the series provides targeted functional customization:

Food-grade Grade:

Compliant with FDA 21 CFR 177.2600 and EU 10/2011 food contact standards, applicable for kitchenware handles, food processing equipment seals and infant product encapsulation.

Antistatic Grade:

Surface resistance controlled at 10⁶-10⁹Ω, suitable for electronic tools, medical equipment housings and precision instrument packaging.

Eco-friendly Grade:

100% recyclable, free of phthalates and PAHs, passed REACH SVHC 223 testing for global environmental compliance.

Innovative Process Empowers High-Precision Encapsulation Molding

With 21 years of TPR material R&D and manufacturing experience, Zhongsu Wang adopts two-color co-injection technology to achieve 0.2mm ultra-thin encapsulation precision and one-time gradient color molding. The material features stable melt fluidity, good mold adaptability, low shrinkage rate and smooth glossy surface after molding.

The material supports a wide working temperature range of -40℃ to 80℃, retaining stable tensile and tear resistance under low-temperature and high-temperature conditions.
