An overview is presented of TrexeTs MuCell microcellular foam extrasion technology and a description is given of its application to the manufacture of thermoformable PP sheet. The results of pilot scale thermoforming trials carried ont to optimise forming conditions and obtain data abont potential cycle time effects, measurements of the densities, flexnral modnlns and wall thicknesses of the sheets and containers made from the sheets and cell stmcture analysis are presented and discussed. 

On the other hand, syntactic materials may also be thought of as reinforced or filled plastics, with the gas-containing particles being the reinforcing component. This classification is also justifiable in view of the manufacturing technology. The matrix is not foamed chemically, but is filled mechanically with the hollow spheres. Syntactic foamed plastics are thus called physical foams 6,7).

In urethane technology, catalysts are widely used in foam manufacture where two or more catalysts are required to give the desired balance of reaction rates between compounds of differing active hydrogen activity. 

Over 4 billion PETP bottles will be available for colleetion across Europe in 1999. PUR Products has introduced technology into the UK which involves glycolysis of postconsumer PETP into materials for the manufacture of rigid urethane foams for building insulation. This application offers a substantial new market for aromatic polyester polyols derived from glycolised PETP recyclate. PUR(PRODUCTS)LTD. 

EB radiation-cured PVC film surface induces a big improvement in tensile strength and excellent printing ink adhesion and adhesive receptance [302]. PVC foams containing plasticizers, thermally activated blowing agents, cross-linkers, and heat stabilizers have been manufactured by EB radiation technology [303]. 

Nerve Agent Antidote Kit (NAAK or MARK I) consists of an atropine auto-injector (2 mg), a pralidoxime chloride auto-injector (2-Pam-Cl, 600 mg), the plastic clip joining the two injectors, and a foam case. The kit serve as a countermeasure to nerve agents, including tabun (GA), sarin (GB), soman (GD), GF, and VX. Military personnel can receive three MARK I for self/buddy aid. Possible side effects of atropine and/or 2-PAM-C1 are deemed insignificant in a nerve agent casualty. Intravenous atropine and 2-PAM-C1 can also be made available. The MARK I kit is manufactured by Survival Technology, Inc., Rockville, Maryland.
