Reliable Silicone Rubber Sheet - Adjustable Hardness Wide Temperature Range

Product Description

High Tear Silicone Sheet for Heavy Duty Application

1.Product Description
 

Our red industrial silicone sheet is vulcanized with 100% virgin fumed VMQ silicone rubber. Iron oxide red pigment ensures stable color without fading, easy to distinguish from black rubber for equipment color-coded sealing systems.             Different from recycled rubber sheets, it is odorless and non-migratory. It maintains stable elasticity from -60ºC to 250ºC for long-term continuous working, excellent anti-ozone, anti-UV and anti-aging performance, no cracking or hardening after long outdoor service.            Outstanding electrical insulation property makes it ideal insulation pad for transformers and electrical cabinets. Two surface options: double smooth surface (non-stick for molds) and fabric cloth surface (anti-slip & better compression recovery for heat press machine mats).           Support die-cutting, engraving, punching into custom gaskets and pads, available in full customization: whole rolls, cut sheets, strips.

2.Advantages

Extreme Wide Temperature Tolerance	It does not crack hard or brittle at minus 60 ºC, does not deform or melt after long-term use at 250 ºC, and can withstand short-term high temperature impact at 280 ºC. It is suitable for ovens, hot pressing, and metallurgical high temperature equipment.
Excellent Electrical & Weather Resistance	High insulation, anti leakage; Resistant to ozone, ultraviolet radiation, and slight acid-base corrosion, the service life of outdoor and chemical workshops is more than three times that of ordinary rubber.
High Tear & Elasticity	Stretching rate of 350% -700%, repeated compression rebound without permanent deformation, sealed without air leakage, long-term compression without collapse.
Stable Red Color Coding	Special red color for industrial pipelines and equipment seals, which can quickly identify the silicone sealing layer during maintenance and distinguish NBR/EPDM ordinary rubber parts. Special red color for industrial pipelines and equipment seals, which can quickly identify the silicone sealing layer during maintenance and distinguish NBR/EPDM ordinary rubber parts.
Eco-Friendly Non-Migratory	Brand new raw materials, free of plasticizers, compliant with RoHS/REACH, food grade up to LFGB standards, no oil precipitation or contamination of workpieces.

9.FAQ

• Q1: What is the temperature range of industrial silicone sheet?
   
  A: Standard solid silicone sheet works continuously from -60ºC to 230ºC, short peak temperature up to 260~300ºC. Foam silicone sheet is recommended below 200ºC for long service.

 

• Q2: What hardness options are available?
   
  A: Solid sheet: Shore A 20A-80A; foam silicone sheet: 8A-35A. Custom hardness is available.

 

• Q3: Can thickness and size be customized? Can you die-cut gaskets?
   
  A4: Thickness ranges 0.3mm-50mm, standard roll width 1000/1200mm. Die-cut irregular gaskets are acceptable.

 

• Q: Is adhesive-backed silicone sheet available?
   
  A: Single/double side adhesive can be supplied. Ordinary adhesive is not suitable for continuous high temperature; high-temperature adhesive version is optional.

 

• Q5: Is regular silicone sheet oil resistant?
   
  A: Standard VMQ silicone has poor resistance to mineral oil. Fluorosilicone sheet is recommended for oil contact working conditions.

 

• Q6: Is silicone sheet insulating? Do you have flame retardant grade?
   
  A: Our solid silicone sheet boasts exceptional insulation properties, ensuring superior performance in demanding environments. Furthermore, our UL94 V-0 flame retardant silicone sheet provides enhanced safety features for critical applications.

 

• Q7: Are your products environmentally compliant? Can you provide the necessary documentation to verify compliance?
   
  A: Our standard products are crafted to adhere to stringent RoHS and REACH regulations, ensuring environmental safety. We are pleased to provide MSDS and comprehensive test reports upon request.

 

• Q8: Is it possible to obtain samples? What are the conditions regarding MOQ and lead time?
   
  A: We offer samples of our standard sizes for your evaluation. For stock orders, expect a prompt delivery within 3-5 days. Customized orders are meticulously crafted and shipped within 7-15 days. Our MOQ terms are flexible and open to negotiation.

 

• Q9: How should one decide between using a solid silicone sheet or a foam silicone sheet?
   
  A: Choose a solid sheet for exceptional compression resistance and optimal tight sealing, ideal for static sealing and high-temperature platens. Opt for a foam sheet when the application requires effective vibration damping, thermal insulation, and efficient gap filling.

 

• Q10: Does the silicone sheet deteriorate quickly when used outdoors?
   
  A: Silicone exhibits superior resistance to UV rays and ozone, outperforming general rubber. For prolonged outdoor applications, our specially formulated anti-UV modifications are highly recommended to ensure durability and longevity.
