DB 886 ke sephutheloana se phahameng sa ts'ebetso sa UV se entsoeng

bakeng sa lisebelisoa tsa polyurethane (mohlala, TPU, CASE, RIM flexible foam applications).

DB 866 e sebetsa hantle haholo ho thermoplastic polyurethane (TPU). DB 866 e ka boela ea sebelisoa ho koahela polyurethane holim'a seile le fatše hammoho le letlalo la maiketsetso.

Lisebelisoa

DB 886 e fana ka botsitso bo ikhethang ba UV ho litsamaiso tsa polyurethane.
