PEKK compounds, material for extrusion-based 3D printing processes and an endothermic blowing agent are highlighted.

Lehvoss North America, part of the Lehvoss Group, will showcase three new products at NPE2018 (Booth #531147). A major focus of the exhibit will be on the company’s customized material solutions and its expanding capabilities in custom compounding, additive manufacturing, masterbatch and concentrates.

A new addition to the Luvocom product line, Luvocom 1114 is designed to provide exceptional tribological and thermal properties. Based on the high-temperature resistant polymer PEKK, Luvocom 1114 offers a number of advantages in tribological applications when compared to other high-temperature polymers such as PEEK. According to Robert Healy, Managing Director, Lehvoss North America, “The wear and friction characteristics of compounds from the Luvocom 1114 line exhibit a low and particularly uniform curve up to 165 C (329 F). Luvocom 1114 also has an elevated heat-deflection temperature.”

Another new Luvocom product, Luvocom 3F, is designed for extrusion-based 3D printing processes including fused filament fabrication. “The product line is dedicated to easy 3D printing with excellent mechanical properties,” says Healy. “Polymers are tailored to 3D printing for different processes and offer improved layer bonding and enhanced printability. The injection molding quality of printed parts is 100 percent consistent.”

Also featured will be Luvobatch PA BA 1001/1002, an endothermic blowing agent that makes it possible to reduce the weight of reinforced polyamides (PA). “Polyamides with reinforcing materials such as glass fibers, carbon fibers and minerals are becoming increasingly important in weight reduction,” says Healy. “Using the Luvobatch PA BA 1001/1002 blowing agent reduces the weight of these materials by up to 30 percent and simultaneously maintains a low level loss of mechanical properties.”

The endothermic blowing agent is specially adapted to polyamides. It helps avoid sink marks and contraction cavities. “Using Luvobatch PA BA 1001/1002 as the carrier system reduces or prevents the delamination in components subject to high mechanical stress which may arise during the addition of masterbatch based on polyethylene or universal carriers.” The system can be used in all common processing techniques.

  • Next Generation Plastics Workforce

    After years of closely monitoring an increasingly worrisome labor shortage, the Plastics Industry Association’s warnings about the widening gap between the sector’s need for skilled workers and the supply of such employees have shifted to full alarm. The association calls for “collaborative response across all levels of government and all manufacturing sectors” to tackle this critical issue.
