MOIIN Flex Clear

For the 3D printing of highly flexible transparent objects with excellent strain recovery properties

Flexible recovery champion.
MOIIN Flex Clear is extremely elastic, offers high elongation at break and exceptionally good strain recovery – even at high temperatures! A further benefit is its excellent chemical resistance. MOIIN Flex Clear is therefore ideal for seals and shock absorption, ergonomic padding, e.g. in the sportswear sector, and for a wide range of further applications where traditional stretchable materials such as rubber or silicone come into use. The high UV resistance and low water absorption of the material also make it particularly resistant to weathering. MOIIN Flex Clear is therefore also excellently suited for a wide range of outdoor applications and process engineering systems.
