DESCRIPTION

A family of low-molecular weight PPE (Polyphenyleneether) oligomers with reactive end groups designed for property enhancement in thermoset formulation. Functional end groups enable use in epoxy, cyanate esters, urethanes, phenolics, phenoxy resins, and free-radical cure systems. These oligomers have solubility in common solvents and some liquid thermosets and curing agents. Potential property enhancements include lower dielectric properties, increased thermal performance, increased toughness, lower moisture uptake and increased flame retardancy. Application areas include printed circuit boards (PCB), composites, encapsulants, adhesives, and coatings. These oligomers can be substituted for reactive diols in polyurethane formulations and can be used as a thermoplastic material for blending in styrenic block copolymers or cured rubber.

BENEFITS

GOOD BALANCE OF PROPERTIES

Tailorable heat resistance, good hydrolytic stability, high dielectric strength and optional non halogenated flame retardants in a low specific gravity material. May be designed to replace stamped steel, die cast metal, and brass in functional assemblies. Compatible with multiple filler technologies to further tailor desired properties.

STIFFNESS AND STRENGTH

High stiffness and tensile & flexural strength, even at elevated temperatures, with only gradual reduction in modulus as temperature is increased, a key advantage

CREEP

Good creep resistance, even at elevated temperatures, thanks to the material‘s inherent high heat resistance, made even better with the addition of various filler systems

IMPACT STRENGTH

Predictable impact strength that remains virtually unaffected by humidity

GOOD ELECTRICAL PERFORMANCE

High dielectric strength with excellent electrical properties

GOOD FIRE RETARDANCY

Available in non-halogen based fire-retardant grades, helping products comply with a broad range of environmental standards, including UL94 V-0. In addition to low toxicity in accordance with GEI 02.37.2, select grades have been designed to meet low smoke requirements in transportation segments

CHEMICAL RESISTANCE

Generally good resistance to acids, bases and many cleaning agents.

HYDROLYTIC STABILITY

Excellent hydrolytic stability, with water absorption rates among the lowest of any engineering thermoplastic

LOW MOLD SHRINKAGE

Excellent dimensional control with exceptionally low mold shrinkage factors

PPO Noryl SE1GFN3 is a 30% glass reinforced, injection moldable modified polyphenylene e ther resin. Designed for improved dimensional stability and good flow , this resin also uses non-chlorinated, non-brominated FR additives to achieve a V1 UL94 rating at 1.5 mm and UL94 5VA rating @ 3.0 mm. NORYL SE1GFN3 may be an excellent material candidate for electrical or electronic applications requiring good rheological properties, heat resistance, hydrolysis resistance, low density and thin wall flame resistance. SE1GFN3 is halogen free according to VDE/DIN 472 part 815.
