ChemFlexx TOTM

TCC’s ChemFlexx TOTM is a nearly colorless oily liquid, free of foreign materials. It is a primary branched monomeric plasticizer produced for polyvinyl chloride homopolymer and copolymer resins. ChemFlexx TOTM is recommended for use in end-use areas where extreme low volatility is required.

ChemFlexx TOTM is a lasting primary plasticizer with the good points of both polyester and monomer plasticizers. The compound is suitable for PVC, cellulose nitrate, ethyl cellulose and poly methyl methacrylate. With above average electrical properties, it is mainly used in electrical wire and cable for 105°C level applications. Other end uses include sealing gaskets and similar products.

Description

The Chemical Company’s (TCC) ChemFlexx TOTM (Tri-2-ethylhexyl Trimellitate) is a primary branched monomeric plasticizer for polyvinyl chloride homopolymer and copolymer resins. Trimellitate plasticizers are an alternative for phthalate plasticizers when high temperature applications and low volatility are important.

TCC’s ChemFlexx TOTM exhibits low migration properties and extraction resistance properties that are required for dishwasher gaskets, medical tubing and photograph storage. In appropriate situations, ChemFlexx TOTM plasticizer can also be blended with other lower volatility plasticizers such as DUP and DOTP.

Plasticizer Overview
Plasticizers are polymer additives that serve to increase the polymer’s flexibility, elongation and ease of processing. In other words, they make the polymer more workable. In technical terms, the addition of a plasticizer generally causes a reduction in the cohesive intermolecular forces along polymer chains. The chains can then move more freely relative to one another, hence reducing the stiffness of the polymer.

The use of plasticizers began in the mid 1860s when castor oil was added to Cellulose Nitrate. The most commonly measured physical effects include melt viscosity, elasticity modulus, and the glass transition temperature. Other types of plasticizers have been used through the years, but in the late 1930s, phthalates were introduced because they were believed to be less toxic. The two most common plasticizers used today are di-2-ethylhexyl phthalate (DEHP) and di-isononyl phthalate (DINP), both of which are generally used in the manufacture of PVC related products.

The Phthalate Plasticizer Market
In 1999, the global volume of plasticizers was approximately 10 billion lbs., or about $5 billion, The market has had an average yearly growth rate of 2-3 percent.

Of these plasticizers, standard phthalate esters comprise over 85 percent of the tonnage produced every year. Phthalates command the market due to their low cost, ease of use and availability. Other common plasticizers include adipates, polymerics and trimellitates.

Over 90 percent of plasticizer volume goes into flexible PVC applications. Plasticized PVC polymer is found in a wide variety of products including food packaging, construction materials, toys, and medical devices. Yet PVC in its “true” form is a hard, brittle polymer used in PVC pipe for the construction industry.
