- Roto resins.
AARDVARK POLYMERS. LAMBERTVILLE. N.J. This polymer producer's new offerings include an FR. nylon with UL94-V0 ratings and the first commercial Aardalloy thermoplastic alloy products. Aarlon 4055FR is a premium flame retardant-type 6/6 polyamide with a UL94V0 rating for flammability. It is formulated without heavy metals or red phosphorous and is ......
- Near-Hermetic, Thermoplastic MEMS Packages Advance
Epoxies are the workhorse polymer for electronics found in most plastic packages, encapsulants and underfills. These compounds are notable for their balance of properties, since they typically contain more filler than epoxy resin to tame the high coefficient of thermal expansion (CTE) mismatch among packaging materials and silicon. Epoxies belong ......
- Not your same old polymers: same monomers, new polymers.
Controlled polymerization techniques provide the chemist with opportunities to customize polymers. The polymers made with these techniques are not only defined by their composition, molecular weight, and polydispersity index, but also by their synthesis method--demonstrated with two AB block copolymer dispersants prepared by GTP and ATRP. [ILLUSTRATION OMITTED] Using these ......
- Engineering Thermoplastics.
Expect to see numerous entries in automotive engineering thermoplastics at NPE, including a totally new amorphous thermoplastic that is said to provide a breakthrough in color and gloss retention outdoors without painting. Besides exterior body panels, new automotive materials for under-hood, interior, structural, and mechanical parts like gears will also ......
- Longer-Chain PP Copolymers Have Very High
MFR.
The first four grades of a new family of polypropylene copolymers come out of the reactor with relatively narrow molecular-weight distribution and longer-than-normal polymer chains. The result is a combination of high melt-flow rate and superior physical properties suitable for injection molding thin walls and living hinges. Montell Polyolefins, Wilmington, ......
- Additives.
This year's show will present such a large number of new polymer additives that only a few categories can be covered this month: antioxidants, halogen and non-halogen flame retardants, PVC heat stabilizers, and impact modifiers. Next month, we'll report on new uv stabilizers, colorants, additive concentrates, lubricants, and more. New ......
