A plastic pallet ( ) having good load bearing construction and held together without mechanical fasteners, includes deck boards ( ). The deck boards include ridges ( ) on an upper side ( ) and a lower side ( ) thereof. Deck boards are positioned transversely on stringers ( ) and joined thereto by either an adhesive or thermoplastic welding processes. The stringers and deck boards may be provided with end caps ( ) which seal interior areas of the stringers and deck boards and prevent tearing thereof. The stringers and deck boards have interior reinforcement ribs ( ). The cross sectional profiles of the stringers, deck boards, and end caps provide a cost effective and light weight pallet. Openings which extend between the stringers allow for either two way fork entry and/or four way fork entry. The stringers and deck boards provide flexibility in constructing pallets of various designs. The plastic pallet preferably is highly durable and fully recyclable.

A shaped rigid thermoplastic cradle and leveler for vessels such as sanitaryware is disclosed. The cradle and leveler are separately formed or integrally shaped from a single thermoformed sheet of rigid thermoplastic material. The rigid thermoplastic material has a flexural modulus of at least about 300,000 psi to provide sufficient rigidity in the sidewall of the cradle. The leveler includes an integral floor leveling means for providing a designed pitch so as to conform to the desired pitch of the floor region of the vessel toward the drain hole. The floor region comprises a plurality of tapering, alternating upper and lower contacting regions. Between each adjacent upper contacting region is defined unsupported span regions having the shortest distance between adjacent upper contact regions of not more than 12 inches (30.5 cm). Preferably the shortest distance between adjacent upper contact regions defining the unsupported span is from 2.5 inches to about 6 inches. A variety of rigid thermoplastic materials are adaptable herewith and include acrylonitrile-butadiene- styrene copolymers, styrene-acrylonitrile copolymer, acrylonitrile-styrene-methacrylate copolymers, polystyrene, styrene-alpha methyl styrene copolymers, polyethylene, polypropylene, polycarbonate, and polyvinyl chloride. The most preferred embodiment comprises rigid fiber reinforced polyvinyl chloride.

Rigidizer for plastic vessels

This invention relates to a process of producing elastomeric particles, such as those of natural and synthetic powdered and crumb rubbers and to the compositions prepared in accordance with such process. Specifically, the invention comprises encapsulating the elastomeric particles with a coating or film of a preplasticized vinyl resin, such as, for example, polymers and copolymers of vinyl and vinylidene halides and the like. The resultant composite particles are free-flowing and free of irreversible agglomeration and can be used in dry-blending with other materials prior to being formed into useful articles.

Process for producing elastomeric particles free of agglomeration

Particulate rubber is intimately and uniformly coated with an anti-cake(s) and pressed at mild temperatures to form friable rubber bales. The bales have a bulk density from about 1.3 to about two times that of the original particulate rubber and are capable of being handled as a slab and of supporting a direct load, yet break down under shear to form particles substantially similar in size and distribution to that of the original particulate rubber.
