Abstract
(A1) Ein aus wenigstens einem thermoplastischen oder thermoelastischen, synthetischen und/oder natuerlichen Polymer sowie natuerlichen Verstaerkungsfasern bestehender Werkstoff zeichnet sich dadurch aus, dass er als natuerliche Verstaerkungsfasern Hanffasern enthaelt. Besteht der erfindungsgemaesse Werkstoff aus mehreren Polymeren, so kann dieser homogen oder heterogen aufgebaut sein.

 

DE 19852067 A UPAB: 20000712 NOVELTY - The material, to be reinforced by fibers, is composed of at least one thermoplastic and/or thermoelastic synthetic and/or natural polymer. The reinforcement is through the addition of natural fibers, and preferably of hemp. DETAILED DESCRIPTION - The material is composed of a single polymer, or a polymer blend of synthetic and/or natural polymers. The material can be a compound polymer material in one, two or more layers, of synthetic and/or natural polymers. The natural polymer is lignin, and especially an alkali lignin solution. USE - The material is used for thermal and acoustic insulation applications. It can also be used as molded components with a wood appearance for window frame profiles, doors, furniture or housings. ADVANTAGE - The material is largely of natural products, with good insulation properties, which can be a substitute for plastics and mineral fibers which pose a health hazard.
