Bay Area Technical Rubber Goods Company snapped up by not so ‘Little’ Goodyear. Goodyear Rubber Co of So Ca is proud to announce the purchase of Berkeley California’s Poly Seal Industries from Dan Baker. Poly Seal had been manufacturing high quality rubber molded products for various industries since 1974. The purchase is effective January 1, … Continued
Hi everyone, I get a lot of lot of molding requests from perspective customers. These prospects are almost never experts in rubber molding. Sometimes they will have had a plastic part molded in the past so the request often comes as something like this: ‘Do you do that injection molding?’. We do have injection molding … Continued
Below is a list of single coat adhesive selectors for different polymer types: I will write a subsequent blog making a more comprehensive list including 2 coat systems. Hope it helps.

Goodyear Rubber knows the value of EPDM (ethylene propylene diene terpolymer) as a durable synthetic rubber used in a variety of application needed strong heat resistance and excellent weathering properties. That’s one reason it is used for roofing. Its two primary ingredients, ethylene and propylene, come from oil and natural gas. Factors that impact economics … Continued
As you might suspect, there are manufacturing concerns and proposed solutions to them when compounding rubber with additives. Inconsistent weighing caused by high scrap: Think about using pre-mixed, oil treated powders. They are easier to weigh and cleaner to handle. They are delivered to the compounding plant surface wetted for faster mixing and multi-ingredient for … Continued

The latex fluid that leaks from rubber trees contains isoprene molecules like many plants and trees. Isoprene, as it dries, bumps into other molecules and reforms with electrons eventually ending up in chain-like strands. Called polyisoprene polymer, the strands cling together much like the opposite poles to magnets. The rubber fibers are held together by … Continued
Modulus is the force required to stretch a defined specimen of rubber to a given percent elongation. Most often, modulus is reported at 300% elongation (four times the original length). This can also be viewed as the resistance to a given elongating force. For an uncompounded elastomer, elongation is primarily a function of stretching and disentangling … Continued
These oils are used as Process Aids in rubber compounds. Processing aid – to assist mechanical breakdown reduce uncured compound viscosity permit incorporation of fillers reduce internal friction in mixing, calendering and extrusion reduce durometer or modulus This blog will talk just a bit about some of the different types of oils in use in … Continued
