Fire-Resistant Silicone Rubber

Compared to standard silicone, this is superior fire-resistant rubber material. It is difficult to ignite even when exposed to flames and when it burns, it hardens into a ceramic-like structure

Typical silicone rubber burns and turns into ash. GKS20258 is fire-resistant and hardens into ceramic-like structure. It maintains its shape with minimal deformation even after burning.

Regulatory Information

Our company has earned various certificates in the thermal interface material field. Some certifications show parent & sister companies, not FUJIPOLY Europe B.V.

Our Process

01

Consultation and Coordination

The Customer would put a simple inquiry. A technical Support Engineer would go through the inquiry and generate the necessary drawings through specific dimensions. This would lead to a quote being sent out to the customer for final approval from both B2B parties. 

02

Making Sample Request

If approved, the customer would be able to request a sample of the material that they have requested from the initial Consultation and Coordination. 

03

Order Confirmation

If approval has been completed, an official order would be sent across to Fujipoly Europe B.V. that the Customer Service Department would prioritise to make sure that the order would be completed on time. 

Frequently asked questions

Information about how ZEBRA Connectors work, the benefits, application methods, or safety considerations.

How do you calculate a “slot dimension” in the connector holder?

The volume of the slot should be equal to or slightly greater than the volume of the connector. Consider all tolerances when determining the max volume of the connector. E.g.; Connector H x W x L= Volume

What is Fujipoly America’s UL file number?

Fujipoly’s UL file number is E58126.

What is the “Aspect Ratio” for a Zebra® connector?

A minimum aspect ratio of 1.5 to 1 is recommended. The aspect ration only applies to the Zebra itself and not the optional support material.

What is the compression set of a connector?

Compression set for a plain Zebra (Silver, Carbon, or Low-Temp) is 10% to 15% of the compressed amount. Compression set for a supported Zebra is 30% to 40% of the compressed amount.
