Recycled polypropylene modified with hydrogenated styrenic block copolymers for automotive applications

Polypropylene (PP) is one of the most widely used polyolefins owing to its low density, low cost, high softening temperature and easy processing. PP is used in the form of molded pieces, sheets, films and fibers in medical, cosmetic and electronic applications. In the automotive industry, it represents 9% of the market, and is used in dashboards, door panels, bumpers and grilles. PP based composites are increasingly becoming preferred materials in automotive applications, and in particular for both exterior and interior parts. In the automotive industry, PP based composites are generally used for the manufacture of bumpers.

The world today uses 12,000 medical gloves per second. Prior to the UP publication, U.S. glove production had been satisfied by a number of medical device manufacturers, namely, Safeskin, Ansell, Aladan, Baxter, Smith & Nephew and Johnson & Johnson. In addition, glove imports in the U.S. prior to 1985 were 1 billion pieces. In 1996, imports exceeded 21 billion pieces.

Use of Tire-Derived and Scrap-Derived Polymers in Tire and Non-Tire Applications

March 18, 2021 RubberWorld 4594 Views 2021, March, micronized rubber, recycle, scrap rubber, scrap tires, tire derived fuel

The disposal of scrap rubber has been a concern since its vulcanization with sulfur and heat was accidentally discovered by Charles Goodyear in 1839. In addition to the scrap generated in production, there is the question of discarded rubber goods that have outlived their usefulness for their original function. Traditionally, this waste had ended up in landfills, contributing to the growing problem of overcrowding. Scrap tires are a well-publicized category of scrap rubber, as each year automobiles produce 246 million waste tires in the United States alone.

Synthesis of reduced graphene oxide/clay nanohybrid: Efficient adsorbent for CO2 and flame retardant

February 19, 2021 RubberWorld 1023 Views 2021, February, flame retardant, graphene clay, nanomaterial

Research shows the development of a graphene/clay hybrid which is an eco-friendly material with air purification capability, and which can also serve as a flame retardant additive in polymers. Two-dimensional nanomaterials like layered silicates, graphene and layered hydroxides (LDH) have been widely studied due to their high aspect ratio, which in turn enhances properties like flame resistance, mechanical properties, gas adsorption, barrier properties and water purification.
