What is LAPEX PPSU<\/span><\/h1>\n

 <\/p>\n

The LATI LAPEX series PPSU (polysulfone) is widely used in electrical, medical, aviation and industrial fields due to its stable thermal performance, flame retardancy and excellent mechanical strength. This series includes three models: PPSU R, PPSU R G\/10, and PPSU R G\/20, covering different formulations from no glass fiber to 20% glass fiber reinforcement, to meet the differentiated requirements of purchasers for dimensional stability, strength and toughness.<\/span><\/p>\n
