Latex today with Jim Finn: The Lightning Round
The objective here is to provide a list of common latex types, their key characteristics, and a summary of their useful properties and contributions. It is unlikely that the summary will capture all the salient points of each latex type; but it should provide enough information to be useful if called upon to deliver a “30 second commercial.”

In industry first, Goodyear launches tire with Monolith’s carbon black
Monolith announced the first of its products to appear in any tire. The Goodyear Tire & Rubber Company (Goodyear), one of the world’s largest tire companies, announced it will use Monolith’s carbon black in a new tread formulation for its ultra-high performance, all-season ElectricDrive™ GT passenger tire in size 235/40R19, which is an ideal fit for vehicles such as the Tesla Model 3. Monolith and Goodyear are taking the next step on the journey toward zero-emissions carbon black in tire manufacturing.

Researchers develop new fiber composite material with cellulose reinforcement fibers
The German Institutes for Textile and Fiber with the project partners CG TEC, Cordenka, ElringKlinger, Fiber Engineering and Technikum Laubholz are developing a new fiber composite material (CELLUN) with cellulose reinforcement fibers. The matrix of the material is a thermoplastic cellulose derivative that can be processed in industrial processing methods such as hot pressing or pultrusion. CELLUN made from renewable biopolymers enables the replacement of glass or carbon fibers in the manufacture of industrial molded parts.

Synthetic leather combines genuine leather qualities with sustainability
Synthetic leathers made from silicone (Si) have superior tactile feel, durability, recyclability, ease of cleaning and inherent fire resistance, but have poor abrasion and cratch resistance due to the inherent properties of silicones. LuxSense is a first of its kind silicone-organic hybrid synthetic leather that combines the benefits of both to become the first synthetic leather that competes with authentic leather on performance, and exceeds all leathers on sustainability.
