Material Strength

Material Strength

➊ Non-Toxic and Safe
Contains no chlorine or plasticizers, eliminating concerns about dioxins. Fully compliant with RoHS, REACH, and USP Class VI standards.
➋ Comfortably Flexible
Designed for prolonged contact with the human body—soft yet structurally stable. Ideal for urinary catheterization, drainage, and fluid delivery.
❸ Durable and Resilient
Offers superior mechanical strength compared to silicone and PVC. Resistant to tearing, cracking, and deformation over time.
➍ Process-Friendly Manufacturing
Excellent processing versatility helps reduce production costs and improve consistency across extrusion and molding applications.
➎ Broad Hardness Range
Available in a wide Shore hardness spectrum (60A to 74D), supporting diverse medical device designs and performance requirements.
➏ Supports Sustainable Healthcare
Aligned with ESG goals and global green trends, enhancing product value and brand image through environmentally conscious material choices.

Property / Material	TPU （Thermoplastic Polyurethane）	Silicone	PVC
Biocompatibility	★★★★☆ Free of plasticizers and chlorine; low tissue irritation	★★★★★ Excellent biocompatibility; suitable for implant-grade applications	★★☆☆☆ Requires plasticizers (e.g., DEHP); potential toxicity risk
Softness & Elasticity	★★★★☆ Soft with good support and resilience; not easily bent or broken	★★★★☆ Very soft and tissue-conforming, but prone to collapse	★★★☆☆ Initially soft but prone to hardening with aging
Mechanical Strength	★★★★☆ High tensile and tear resistance; durable and flexible for long-term use	★★★☆☆ Soft but loosely structured; less wear-resistant	★★☆☆☆ Poor tensile and abrasion resistance; prone to cracking/deformation
Processability / Manufacturing	★★★★★ Excellent thermoplasticity; suitable for injection and extrusion; highly efficient	★★☆☆☆ Requires vulcanization; slow and costly process	★★★★☆ Good thermoplasticity; easy to process
Transparency & Appearance	★★★★☆ High transparency; can be colored; suitable for observing fluid flow or product design	★★★☆☆ Moderate transparency; typically matte finish	★★☆☆☆ Generally milky or gray-white; difficult to achieve high transparency
Barrier to Gas & Liquid	★★★★☆ Good barrier properties; resistant to water vapor and drug permeation	★★☆☆☆ High permeability; gas and drug molecules easily pass through	★★★☆☆ Moderate barrier; risk of plasticizer migration
Environmental & Safety Profile	★★★★★ Chlorine-free, DEHP-free, recyclable; non-toxic when incinerated	★★★★☆ Safe to use, but manufacturing is less eco-friendly	★★☆☆☆ Contains chlorine and plasticizers; incineration produces dioxins
Drug Resistance & Sterilization	★★★★☆ Compatible with EtO, gamma, and steam sterilization; retains integrity	★★★☆☆ Resistant to EtO; long-term steam may affect material stability	★★★☆☆ Compatible with some methods; may deform under high heat
