SI Group Solutions for Building and Construction Plastics

The building and construction market projects a rapid recovery and accelerated growth in the United States over the next few years. This is driven by an increased demand for single-family housing and a recovering market for commercial buildings.
Polyolefins and plastic materials utilize various performance additives and stabilizers to improve the durability, resistance, and endurance of plastic composites for use in building and construction applications.

ChemPoint offers a comprehensive portfolio of antioxidants, stabilizers, and compatibilizers from SI Group that can help you achieve the desired quality in your plastic materials.


Antioxidants are used in various resins to inhibit the oxidative degradation of polymers by preventing the propagation steps of oxidation that occur during the initial manufacturing, fabrication, or subsequent exposure to the environment and extreme conditions.

Light Stabilizers:

Light stabilizers or UV stabilizers are specialty additives that inhibit the degradation of plastic materials by ultraviolet light. Light stabilizers prevent damages to the plastics' visual and physical properties caused by exposure to UV light. Benzophenones are used as general-purpose UV absorbers in transparent and light color plastics. Hindered amine light stabilizers (HALS) are the most effective light stabilizers and can be used in a wide range of polymers and plastic applications.

Polymer Modifiers and Compatibilizers:

Compatibility of fillers with the polymer matrix is essential for the stability and strength of plastic formulations. POLYBOND™ polymer modifiers and compatibilizers unleash fillers' potential by improving the bonding and dispersion of fillers to the resin's matrix. This can help you achieve the desired resistance, strength, and mechanical properties.

POLYBOND™ 3200 and 7200 are excellent compatibilizers from SI Group that act as a coupling agent for natural fiber fillers in polypropylene and polyethylene formulations. They are a perfect choice for plastic composites in building and construction applications, including decking, flooring, siding, and cladding.

POLYBOND™ 3200 is very effective at enhancing the mechanical properties and improving the flexural strength of natural fibers and plastic compounds at a low level of use.

POLYBOND™ 7200 offers long-term performance to composite decks by reducing water uptake and increasing fluid resistance. At low dosage levels, POLYBOND™ 7200 improves the flexural strength and reduces water absorption in wood composites by up to 50%.
