Emulsification and baking

Mono- and diglycerides of fatty acids

For mono- and diglycerides, specify the monoglyceride fraction, fatty acid source and carrier. Verify performance in the actual baking or emulsion formula.

Preservation and oxidation control

Mixed tocopherols

For mixed tocopherols in fat-containing systems, check total tocopherols, homologue profile and carrier. Evaluate oxidative stability in the finished product.

Base resins and elastomers

Polyethylene resins

Select polyethylene for the intended process. Blown film, injection molding and blow molding require different grades.

Base resins and elastomers

Polypropylene resins

Homopolymer, random copolymer and impact copolymer PP offer different balances of stiffness, clarity and low-temperature impact resistance.

Base resins and elastomers

ABS resins

For ABS, compare color, impact resistance, flow and heat resistance on the same grade sheet. Request supporting data for flame-retardant or plating grades.

Base resins and elastomers

Styrene-butadiene rubber (SBR)

Separate emulsion and solution SBR, and oil-extended and non-oil-extended grades. Align rubber and oil inputs before comparing compound performance.

Base resins and elastomers

Polybutadiene rubber (BR)

Polybutadiene microstructure, molecular weight distribution and processing viscosity affect filler dispersion and wear resistance.

Base resins and elastomers

Ethylene propylene diene rubber (EPDM)

For EPDM profiles, seals and extrusions, check ethylene and diene content, viscosity and whether the grade is oil extended.

Base resins and elastomers

Nitrile butadiene rubber (NBR)

Start NBR selection with acrylonitrile content and viscosity. Verify fluid resistance and cold performance in the actual part.

Base resins and elastomers

Natural rubber (NR)

Specify the commercial natural rubber type, such as technically specified rubber or ribbed smoked sheet. Mooney viscosity and natural impurity limits are separate requirements.

Fillers, reinforcement and coupling

Kaolin

Distinguish water-washed, calcined and surface-treated kaolin. Particle size and treatment are often more informative than whiteness alone when selecting a filler.

Bis[3-(triethoxysilyl)propyl] tetrasulfide (TESPT)

TESPT is used in silica-filled rubber. Compare neat silane content, sulfur chain distribution and any carrier.

Vulcanization, activation and scorch control

Sulfur for rubber vulcanization

Distinguish conventional, insoluble and oil-treated sulfur grades. Commercial product weight does not equal active sulfur weight.
