Abstract
The present invention relates to a composite elongated body (3), comprising high performance polyethylene HPPE filaments (2) having a tenacity of at least 0.6 N/tex and a polymeric composition (10) present throughout the composite elongated body, wherein the polymeric composition comprises a thermoplastic ethylene copolymer and a polysiloxane; and wherein the thermoplastic ethylene copolymer is a copolymer of ethylene and wherein said polymeric composition has a peak melting temperature in the range from 40 to 140° C.
Claims15
A composite elongated body, comprising high performance polyethylene HPPE filaments having a tenacity of at least 0.6 N/tex and a polymeric composition present throughout the composite elongated body,
- wherein the polymeric composition comprises
- a) a thermoplastic ethylene copolymer;
- and
- b) a polysiloxane;
- and wherein the thermoplastic ethylene copolymer is a copolymer of ethylene and
- wherein said polymeric composition has a peak melting temperature in the range from 40 to 140° C., measured in accordance with ASTM E794-06.
A method of manufacturing a composite elongated body comprising the steps:
- a) providing a coating composition, wherein the coating composition comprises
- a thermoplastic ethylene copolymer;
- a water;
- and
- a polysiloxane;
- b) providing at least two HPPE filaments, the filaments having a tenacity of at least 0.6 N/tex;
- c) applying the coating composition to the filaments to obtain coated filaments;
- and
- d) elevating the temperature of the coated filaments to obtain the composite elongated body,
- wherein the thermoplastic ethylene copolymer is a copolymer of ethylene and wherein said thermoplastic ethylene copolymer has a peak melting temperature in the range from 40 to 140° C., measured in accordance with ASTM E794-06.
