ProdUct descriPtion

Unifilo ® is an E-glass continuous strand mat of random orientation in multiple layers and held together with a binder. All 700 series Unifilo ® mats are designed to be preformed at the © Celtite same dimensions than the moulded part. These Unifilo ® U700 are all compatibles with UP, UP(V), PU, and EP resins for boats and are used for injection moulding (RTM , SRIM) and compression.

•

U720: automatic preforming process

•

U740, U746, U750, U756: for the manufacture of preforms and moulding with filled resins

•

Unitop T700: special product with transverse oriented properties.

•

Unistretch S700: specially designed with high deformability rate during preforming
