PROTECTIVE ELEMENTS MADE OF POLYOLEFIN HOT-MELT ADHESIVES |
| 摘要 |
The use of a hot-melt adhesive as a protective element for objects is disclosed, wherein the hot-melt adhesive contains over 80 wt. % of at least one modified polyolefin copolymer produced from a high-molecular-weight polyolefin copolymer by thermomechanical degradation of the polymer under shear stress and/or heating, wherein the viscosity of the copolymer is reduced, and up to 20 wt. % of additives and auxiliary substances, wherein the adhesive has a softening point from 70 to 150° C. |

1. A protective coating element prepared from a hot-melt adhesive comprising:
(a) greater than 80 wt. % of at least one modified polyolefin copolymer produced by thermomechanically degrading a high-molecular-weight polyolefin copolymer under shear stress and/or heating, whereby the viscosity of the copolymer is reduced, and (b) up to 20 wt. % of an additive and auxiliary; wherein the adhesive has a softening point from 70 to 150° C. |
