LAPEX R is a family of high-temperature materials with a superior combination of properties. It provides very high heat deflection
temperatures under load together with exceptional hydrolytic stability and resistance to creep at high temperatures.
LAPEX R features outstanding impact properties compared to other high temperature materials. Moreover PPSU offers a good degree of chemical resistance and it is suitable for virtually-unlimited sterilisation cycles.
LAPEX R is intrinsically flame retardant and maintains a UL94V-0 rating at low wall thickness. During combustion it gives low heat release, low smoke generation and low toxic-gas emission so that it is suitable for use in public buildings or aircraft.
To prevent or to reduce internal stresses that may give micro cracking or failure in the long term, correct design and moulding are required. Moreover annealing at 165°C (lh for every mm of thickness) can be performed in order to reduce frozen-in stresses and stress cracking.
LATI is willing to share with you its expertise in this field, and its T.S. and R&D teams are at your complete disposal to analyse your
requirements and collaborate on project developments.
