Polaris™ unsaturated polyester resin

Polaris unsaturated polyester resins provide fabricators with resin options that fit any cast polymer need. Polaris resins are designed for high filler loading, fast green strength development and quick de-mold times without cracking or warping. Polaris resins have excellent batch-to-batch consistency in color and liquid properties. For cultured marble and onyx fabricators, Polaris resins also have excellent thermal shock resistance and low color.

For the solid surface fabricator, Polaris resins will produce void-free solid surfaces that exceed ANSI 124.6 testing requirements for stain and chemical resistance. For engineered stone applications, Polaris resins provide superior strength and surface quality compared to traditional materials. Polaris resins also have good mechanical strength and low water absorption at high filler loading capacity.

Application Information




Cast Marble and Onyx

Polaris resins are used in vanity tops, bath tubs and wall panels.

  • Superior batch-to-batch color consistency and liquid properties
  • Excellent filler loading and filler wet-out
  • Superior resistance to thermal shock
  • Non-porous surface
Engineered Stone

Polaris engineered stone resins are used in countertops. The resins are equal weight to natural stone and have good mechanical strength, low water absorption and high filler loading capacity.

  • Good mechanical strength
  • Low water absorption
  • High filler loading capacity
  • Superior air release
Solid Surface

Polaris acrylic modified solid surface resins are used in countertops. Exceeds ANSI Z124.6 solid surface standards for stain, chemical, and water resistance. Surpassed 10,000 thermal cycles for shock resistance.

  • Non-porous surface
  • Stain-resistant
  • Seamless, so no grout required
  • Excellent design flexibility
  • Easy to clean

Composite polymers mechanical testing

Mechanical testing provides test data to characterize the mechanical integrity of molded resin castings, composites, laminates and sections of molded parts. The data is used to qualify materials for customer specifications, to help design materials for optimum end-use performance or to evaluate the effects of exposure environments on mechanical integrity. The material strength can be evaluated in a variety of deformations:
● Tensile testing – measures the stiffness and strength of a material as it is being pulled apart in tension.
● Flex testing – measures the stiffness and strength of a material as it is being deformed in three-point flexural bending.
● Fatigue testing – applies to a cyclical load or strain to the sample and determines the resiliency or durability of the material by measuring the number of cycles to failure.
