Frequently Asked Questions
Frequently Asked Questions
What is Inner Rubber Outer Fiber Silicone Sleeving used for?
Inner Rubber Outer Fiber Silicone Sleeving is used for electrical insulation and routed protection where heat, flexibility, abrasion or assembly constraints need to be reviewed together.
How do I choose the right Inner Rubber Outer Fiber Silicone Sleeving?
Confirm inner diameter, wall requirement, temperature, voltage, movement, abrasion, oil or chemical exposure and the customer validation document requirement.
What details help WCW Flex recommend samples?
Share the protected part, application photo or drawing, dimensions, color, cut length, packing requirement and any required test or compliance evidence.
What is the construction of inner rubber outer fiber silicone sleeving?
Inner rubber outer fiber silicone sleeving has a composite construction: an inner silicone rubber layer bonded to an outer fiberglass braid coated with silicone. This provides the dielectric strength of a rubber tube with the abrasion resistance and mechanical protection of a braided sleeving, rated at 200 C 600 V under UL File E233803.
When should I choose inner rubber outer fiber sleeving over standard silicone fiberglass sleeving?
Choose inner rubber outer fiber silicone sleeving when the application needs both high dielectric strength from the inner rubber layer and external abrasion protection from the fiberglass braid. Choose standard silicone fiberglass sleeving when a single coated braid construction is sufficient and lighter wall thickness is preferred.
What voltage rating does inner rubber outer fiber silicone sleeving carry?
WCW Flex inner rubber outer fiber silicone sleeving is rated at 200 C 600 V under UL File E233803. The inner silicone rubber layer provides the primary dielectric barrier while the outer fiberglass braid adds mechanical and thermal protection.
