High-Performance Solid General-Purpose Silicone

WENZHOU HEFENG SILICONE RUBBER offers high-performance solid general-purpose silicone materials, including HF-2150J, HF-2160J, HF-2170J, and HF-2180J. These materials are designed for various industrial applications, ensuring reliable performance.

The hardness increases with the grade, ranging from 50±3 for HF-2150J to 80±3 for HF-2180J, offering flexibility for different rigidity needs.

Plasticity ranges from 180±20 in HF-2150J to 280±20 in HF-2170J and HF-2180J, providing flexibility for various manufacturing processes.

Density ranges from 1.17±0.05 g/cm³ in HF-2150J to 1.22±0.05 g/cm³ in HF-2170J and HF-2180J, ensuring consistent quality and performance.

Tensile strength is highest in HF-2150J and HF-2160J with ≥7.5 MPa, and decreases to ≥6 MPa in HF-2180J.

Elongation decreases from ≥400% in HF-2150J to ≥200% in HF-2180J, reflecting reduced stretchability with higher grades.

Compression set at 175°C for 22 hours decreases with higher grades, from ≤10% in HF-2150J and HF-2160J to ≤6% in HF-2180J.

All grades maintain a tear strength of ≥15 kN/m, ensuring durability. Rebound also decreases from ≥45% in HF-2150J to ≥35% in HF-2180J.

These materials are ideal for applications requiring different hardness, flexibility, and durability levels. WENZHOU HEFENG SILICONE RUBBER provides versatile solutions for industries like automotive, electrical, and consumer goods.
