COIM Group has developed and produced specialty polymers in Italy since 1962, with plants and offices on five continents. Laripur is their thermoplastic polyurethane line and Laricol is their reactivable adhesive line. Both are made at the Offanengo plant near Cremona.
The Laripur grades on this page run from Shore A 66 to Shore D 77, in polyester, polyether and polycaprolactone chemistries. Each grade page carries the typical properties from COIM's own technical data sheet, the applications COIM lists for it, the drying and temperature profile, and the packaging.
P.A.T. Products is the North American distributor for the Laripur and Laricol lines and has sold them for close to four decades. Stock is held in the United States and ships across the United States, Canada and Mexico. Samples ship from stock and cross-references to commonly specified TPU grades are available on request.
Extrusion versions carry an end code on the order. COIM identifies them with a code such as EG or AE after the grade number, and that code has to be on the purchase order when the material is going into a die. Tell us the process and we will confirm which version you need.
Special epoxy resin in non-ionic water dispersion. A special epoxy film former whose dried film holds 95 percent of its mass at 725 degrees F, built for chopped strands and tows going into PPS and PEEK. 57 percent solids, cross-linkable, and no curing needed after drying.

Twenty-nine polyurethane dispersions for carbon fiber sizing, with the dried film stiffness published on every grade, from a soft 0.5 MPa film at 880 percent elongation to a stiff 21 MPa one. Most are anionic, many are hydrazine-free, and several are published for virgin or recycled fiber.
