Perlast® G90LT

Perlast® G90LT – An Explosive Decompression Resistant FFKM

Perlast® G90LT is one of the Perlast® Super-Six range of outstanding FFKM compounds. It presents a unique fusion of exceptional chemical resistance, remarkable resistance to explosive decompression, and impressive low-temperature capability, reaching down to -46°C (-51°F). Formulated with precision, Perlast® G90LT offers excellent resistance against a diverse range of chemicals by carefully modulating its molecular structure.

Featuring low permeability, this FFKM is less prone to swelling, ensuring prolonged performance in valves, pumps, and mechanical seals. It’s an optimal choice for exploration and completion applications, as well as equipment operating or stored in sub-zero conditions. Whether for dynamic or static applications, Perlast® G90LT can be seamlessly molded into O Rings (up to 2.5m/8ft internal diameter) and customised shapes to meet specific requirements.
