SI Group Solutions
 

How can SI Group solutions support your infrastructure bid? The SI Group portfolio of chemical additives, from antioxidants to polymer modifiers to UV stabilizers, offers infrastructure components with long-term performance and degradation protection. Resins are chosen based on the property envelope, and stabilization systems ensure the resin properties are maintained for the polymer’s expected lifetime.

 

Adhesives

Adhesives used in industrial construction applications are expected to offer high performance through strength, flexibility, and impact resistance. Antioxidants are critical to protecting against degradation caused by exposure to oxygen, with increasingly demanding regulations and requirements for structural and industrial adhesives.
 

Grade	Chemistry	Summary
ANOX™ 20	Phenolic	General all-purpose antioxidant suitable for moisture-curable hot melt, SBC-based hot melt, nonwoven lamination, and acrylic- and SBC-based PSA
ALKANOX™ 240	Phosphite	General purpose phosphite antioxidant offering synergistic effect with phenolic antioxidant and providing balanced performance in viscosity holding and color in hot-melt adhesives (e.g., polyester hot melt)
NAUGARD™ 445	Aminic	Amine antioxidant and heat stabilizer for toughened cyanoacrylate, PSA tapes, variety types of hot melts, or Epoxy adhesives

Coatings

Infrastructure coatings are required to protect pipes and tanks from the effects of water or chemical exposure. Coatings can lengthen the lifespan and mechanical properties of the equipment and allow for delayed corrosion. SI Group has a range of solutions for industrial coatings, from phenolic resins to antioxidants to UV stabilizers, that not only help maintain structural integrity but also increase the equipment’s functional life.

Grade	Chemistry	Summary
LOWILITE™ 28	Benzotriazole	General-purpose benzotriazole with low base color
LOWINOX™ 44B25	Phenolic	High-activity, nondiscoloring phenolic antioxidant with chemical and hydrolytic stability for polyester resins
ANOX™ PP18	Hindered Phenolic	General-purpose phenolic antioxidant with good solubility

Liquid Coatings Solutions
 

Grade	Chemistry	Summary
ANOX™ 1315	Phenolic	Low-viscosity liquid phenolic antioxidant with good solubility in nonpolar substrates
LOWINOX™ GP45	Phenolic	High molecular weight phenolic antioxidant with very low volatility and excellent resistance to extraction
LOWILITE™ 55	Benzotriazole	UV light absorber that offers a high degree of photostability

Wire and Cables

Wire and cables have a broad range of infrastructure applications, from solar panels to wind turbines to broadband and telecommunications. Insulation and jacketing products created from extrusion may experience a degradation process called water treeing when exposed to moisture or electrical stress. Polyethylene wire insulation can benefit from the exceptionally effective ETHANOX™ 330 antioxidant that protects against degradation from high-temperature exposure.

EV Charging Stations

Electric vehicle charging stations require wire and cable components. Polymer materials, such as polyamides, will also experience significant growth to maximize the EV charger’s efficiency. Whether that includes inner power electronics or EV chargers, pumps, manifolds, system tubing, and connectors must guarantee durability and safety. Thermal management from high-voltage requirements and UV protection is achieved by incorporating antioxidants and light stabilizers.

FEATURED GRADE
ETHANOX® 330 for HDPE Pipe Applications
 

ETHANOX™ 330 antioxidant exhibits superior performance over typical high molecular weight antioxidants in controlling the degradation of polyolefin polymers during processing. Hydrolysis of the ester groups of competitive equivalent antioxidants in deionized water and the resulting migration from PP films were demonstrated via HPLC. ETHANOX™ 330 does not have these ester linkages, thus exhibiting superior resistance to hydrolysis.
 

Why Choose ETHANOX® 330?

• High molecular weight crystalline powder
• Provides long-term stability
• Superior processing stabilizer
• Biologically inert
• Extremely low extractability
• Good benefits in filled and flame-retarded use
• Does not impart odor or color
• Electrically neutral

 

Extraction Resistance of ETHANOX® 330 in HDPE Pipe

Through the extraction resistance test, there is no loss of ETHANOX™ 330.
