PENTAERYTHRITOL TETRANITRATE, also known as PETN, is a highly explosive nitrate ester used in the production of explosives, propellants, and pyrotechnics. It is commonly used in the military, agriculture, and manufacturing industries.
When exposed to PETN, rubber materials are at risk of swelling, cracking, and losing their elasticity. The breaking of the chemical bonds and changes to the molecular structure of the rubber can cause both physical and chemical damage to the rubber. Additionally, the presence of PETN can lead to embrittlement, causing the rubber to become brittle and prone to cracking.
Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
