ORLANDO, FLA. (April 16, 1:30 p.m. ET) — Trelleborg Offshore is launching its high-performance Syntac T-max syntactic material for better mold control in the thermoforming of blister packs.

The composite plug-assist material is a Teflon-impregnated syntactic foam used for processes requiring a high-temperature material with superior slip and release properties.

Trelleborg Offshore produces the material at sites in Mansfield, Mass., and Skelmeresdale, England.

Syntac T-max has good abrasion-resistant properties and a maximum running temperature of 450° F. The material is designed for use on both sheet-fed and heavy-gauge thermoforming.

Jim Payton, sales manager, said Syntac T-max adds another first-class solution to meet the changing needs of Trelleborg Offshore customers.

Also at NPE2012, Trelleborg Offshore displayed its tough Eccolite Ultra syntactic composite material with a formulation that conducts ductility with low thermal expansion at temperatures up to 392° F.

Sales manager Will Ricci said Eccolite Ultra has the toughness to meet stringent standards for thermoforming plastic materials and is compliant with U.S. Food and Drug Administration regulations for use in food packaging.

With Eccolite Ultra, machinists can run intricate details to high cycles, without creating chill or swirl marks or breaking plugs. The material ribbons or chips when machined and keeps machine shop dust to a minimum.

In addition, Trelleborg Offshore is displaying its established Syntac 350 and Syntac 450 materials, which are available off the shelf for a wide range of machinable blocks, rods and sheets.

Originally, Trelleborg Offshore developed and introduced its first syntactic thermoforming material in 1981 and has continued to invest in and develop the product line. Bob Kelly is vice president of global industrial customer solutions.

Trelleborg Offshore, which has an office in Houston, employs 450 in the Americas. The company is part of the engineered systems business of publicly traded Trelleborg, Sweden-based Trelleborg AB.
