Heat-Shrinkable Rubber Tubing <ST Series> - Shin-Etsu …

1 Heat-Shrinkable Rubber Tubing ST SeriesA diverse product lineup for a wide range of industrial ST series are Heat-Shrinkable Rubber tubings made of silicone . Simpl y heating shrinks the inner diameter of the Tubing by about 50%. These silicone Rubber tubings are used for electrical insulation, protection and products in the ST series offer the fine properties typical o f s i l i c o n e , i n c l u d i n g h e a t - a n d c o l d - r e s i s t a n c e , chemical-resistance, excellent weatherability and fine electrical p r o p e r t i e s . T h i s m a k e s t h e m i d e a l f o r a w i d e r a n g e o f applications ranging from roller covers, paint masking and consumer electronics to applications in the transport industry and the light and heavy electric Heat-Shrinkable Rubber tubings offer advantages in saved labor and reduced work time, and exhibit stable performance in even the harshest conditions.

6 Thanks to the excellent release properties typical of silicone form highly airtight the contractile stress of rubbers, the Tubing shrinks tight to the object being covered to form a highly airtight cover. In addition, you can form a watertight seal by injecting RTV wide assortment of lineup includes Tubing in a wide variety of wall thicknesses and bore diameters, from small to high- & low-temperature resistance and flame be used over a wide temperature range (-50 C to +200 C).All ST-DG tubings have high flame retardancy and are UL Rubber TubingST SeriesReading the product number:Size: post-shrink bore diameter x 10 Size Grade Post-shrink (mm) wall thickness (mm)

This cycle is repeated 5 times. 5 test strips are used (flame applications: 25 total), and the material passes only if the flame/glow time per any single flame application never exceeds 60 TypeST-HT TypeST-DG TypeFlame retardant gradeUL certified product (UL-224). Product name and other items are printed on the surface of the tube.
