A new low-emission acetal for automotive and non-automotive gears is said to outperform high-viscosity acetals.
Aardalloy 3300 is a medium viscosity, high heat, homopolymer acetal alloyed with elastomers and modifiers that greatly increase impact strength and elongation compared to unfilled acetals.
In butyl rubber, cyclic acetals are also remarkably more effective than PPDs.
As the pendant group of the acetal will have a tremendous effect on the physical character of the polymer, it is desirable to have an efficient synthesis route for the production of a diversity of poly(vinyl acetals) (28).
This is because the rate of MW reduction in acetals is so rapid at processing conditions that any polymer chains that begin to unzip reach a MW that is so low that they no longer influence the melt viscosity of the polymer.
Aardalloy 3300 POM is a medium-viscosity, high-heat homopolymer acetal alloyed with elastomers and modifiers that increase impact strength and elongation versus unfilled acetals.
The Tg of acetals is -78 C (-109 F), or the temperature of dry ice.
Exhibiting up to 80% less gloss than standard UV-stabilized acetals, Hostaform WR140LG withstands extended UV exposure with little appearance change.
Acetals were known at the laboratory level as far back as the 1920s, but it took until the mid-1950s to solve the problems associated with the thermal stability of the material.
Its stiffness, strength, and toughness are similar to those of standard medium-viscosity acetals.
A new North American compounder claims to offer the industry's first acetals for rotomolding.
