bases, foodstuffs, petroleum, solvents and synthetic surfactants. In the automotive
industry, molded plastic parts may be in contact with drawing fluids. Over time, these
fluids may have an adverse effect on the mating plastic parts, causing them to stress
crack and creating loose parts. DYLARK demonstrates satisfactory performance with
cutting and drawing oils, rust inhibitors, cleaning compounds and rust inhibitors.

Chemical Resistance
DYLARK resins exhibit chemical resistance when exposed at room temperature to acids,bases, foodstuffs, petroleum, solvents and synthetic surfactants. In the automotive
industry, molded plastic parts may be in contact with drawing fluids. Over time, these
fluids may have an adverse effect on the mating plastic parts, causing them to stress
crack and creating loose parts. DYLARK demonstrates satisfactory performance with
cutting and drawing oils, rust inhibitors, cleaning compounds and rust inhibitors.
Computer-Aided Engineering (CAE) and Design
NOVA Chemicals’ CAE center assists customers with advanced part design and computer aided design engineering and processing techniques. Our customers achieve
optimum performance through cross-functional design teams and a closed-loop
engineering process.
NOVA Chemicals also supports high-speed data acquisitions and a 4-stage Level-One
Review of the project's manufacturing feasibility to provide the maximum flexibility
within the budgeted platform schedule and cost.
Injection Molding
Excellent processability is one of the key advantages of DYLARK resins. High melt flow and quick setting characteristics result in faster molding cycles over competitive resins.
DYLARK is processed on injection molding equipment, utilizing standard screw and
barrel designs. Contact NOVA Chemicals' technical support and consult the DYLARK
Best Design Manual for additional information on recommended tooling systems for
molding DYLARK resins.
Long-Term Heat Aging (LTHA) Resistance
LTHA performance at 230°F (110°C) for a 12-week duration matches the 10-year vehicle life cycle performance required for automotive instrument panels. Using a test
method in line with this procedure, DYLARK grades retained 95 to 99% of their
physical properties, including dimensional stability, thermal resistance, color stability,
and flexural, izod impact and elongation property retention.
