We know that all plastics are not alike (public opinion to the contrary), but too often we accept a supplier's product without knowing what's in it that may help or hinder our operations, and, most importantly, in what form and how much.

Whatever you may think about the science supporting the alleged health risks of PVC and phthalates, the marketing battle has been lost. "PVC free" is a slogan that resonates in the public space, much in the same way as gluten free, even when the latter promotes a product that never contained gluten in the first place. Early on, Danish company Melitek (Alslev) has been at the forefront of developing and supplying thermoplastic elastomer and polyolefin compounds for use as PVC replacement materials in the healthcare sector.

By PlasticsToday Staff
Published: October 30th, 2015

German contract molder and manufacturer Raumedic (Helmbrechts) reports that it has developed a method for permanently combining non-polar thermoplastics with silicone elastomers to form a novel adhesive bond. Until now, according to the company, only a handful of polar thermoplastics could be combined with silicone. As for the prevailing hard polypropylene and soft thermoplastic elastomer combination, it comes with a compromise in terms of long-term behavior and resilience.
