Y arsley Research Laboratories of Chessington, England, invite cosponsors for an independent evaluatory project aimed at providing designers with an authoratitive comparison of the more important thermoplastics. Using full scale research and testing facilities established over 40 years, a newly developed technique will be employed to provide information of a meaningful and practica.1 value to processors, particularly injection molders, such that a judicious choice of material will not only minimize molding problems but, by covering such problems as shrinkage, creep, and tendency to fracture when notched, will lead to end products of greater stability.
To obtain a prospectus writ,e direct to The Yarsley Organisation, Clayton Road, Chessington, England.
