NewAge Industries' polyethylene-lined EVA tubing is a co-extruded product that combines the functionality of polyethylene with the flexibility of EVA (ethylene vinyl acetate). Polyethylene tubing is typically a semi-rigid product and the addition of EVA gives it enhanced flexibility and allows its use with economical barb-style fittings. The tubing's manufacturing method ensures a permanent bond between the inner and outer layers. First the core of low density polyethylene is extruded, then farther down the production line, the EVA covering is extruded around the core. The tubing offers different performance characteristics for the inside and outside of the tube: cleanliness inside, flexibility outside.
Produced from Class VI, FDA-sanctioned ingredients, translucent polyethylene-lined EVA tubing is non-toxic, odorless, tasteless and inert. It offers good general chemical resistance and a low friction coefficient. Polyethylene-lined EVA also resists gases and moisture and remains pliable even after extended contact with alcohol. NewAge stocks polyethylene-lined EVA tubing in nine sizes from 1/8 to 1 inch I.D and it can be used in applications such as food and beverage processing, pharmaceutical uses, chemical transfer, appliances, computer equipment, laboratories and fluid feeds and drains.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
