TOMBO™ No. 2670-BNX Rubber O-ring BLAZER NEXT™
BLAZER NEXT is a perfluoroelastomer (FFKM) with excellent heat resistance, radical resistance, purity, and non-stickiness thanks to Nichias’ proprietary cross-linking technologies. It seals in strict environments where other rubber materials struggle.

Features

Heat resistance guide*: 335°C
Standard hardness (Duro A): 76
Compression set at high temperatures is small and it offers stable sealing performance over a long period of time.
*The guide for heat resistance differs according to various conditions.

Applications

Sealing of heat treatment units for manufacturing semiconductors and LCD concerning which heat resistance is particularly necessary (annealing furnaces, LPCVD units, etc)

Sealing of units, piping and valves used in various industrial fields

Compression set test results

Inspected by Nichias

Test conditions

Measurement tool: see the figure above
Test material: O-ring (AS568-214: φ3.53 mm × ID 25.0 mm)
Heating temperature: 300°C
Compression rate: 25% (when heated)

BLAZER NEXT’s compression set at high temperatures is less than that of a general product (FFKM), and it delivers stable sealing performance over the long term.
