All TulipCase mobile phone cases are made with sustainable materials: PBAT, PLA and Wheat Straw. That's why the degradable time is 3-6 months.
80% PBAT (polybutylene adipate terephthalate) is a biodegradable random copolymer, specifically a copolyester of adipic acid, 1,4-butanediol and terephthalic acid (from dimethyl terephthalate). 10% of our cases are made from PLA (Polylactic acid), which is
a thermoplastic aliphatic polyester derived from renewable resources. And the last 10 % are Wheat Straw, which is left over when wheat grains are harvested. Normally this raw material would be thrown away or burned. TulipCase gives it a new life.
