BetaNuc
All in One. Never Seen Before. The only additive that lets you push impact, elongation, hinge life, stiffness, HDT and chemical resistance — all at once.
Dramatic jumps in notched impact strength at just 1% loading — without the cost of impact copolymers.
Up to +100% tensile elongation — parts bend instead of snap, without blending elastomers.
Exceptional flex life for caps, closures and living hinges — survive the cycles others can't.
Keep the homopolymer rigidity that makes PP great — no compromise, no trade-off.
Heat Deflection Temperature is preserved — and slightly improved — so parts hold shape under heat.
Improved ESCR — your polypropylene stands up to harsher chemical environments for longer.
Just add 1% of ASN BetaNuc SX-514 to standard PP Homopolymer — and feel the difference.
ASN BetaNuc SX-514 is a non-elastomeric, beta-nucleating multifunctional modifier developed to transform standard PP homopolymer into a material with superior overall performance — at just 0.5% to 2% loading.
Achieve enhanced impact strength and elongation at break without sacrificing homopolymer stiffness. Replace expensive impact copolymers entirely.
Save money by upgrading standard PP instead of buying expensive copolymers. Reduce raw material costs while improving part performance.
More uniform crystallization delivers better part consistency and fewer rejects across your production line.
Supplied as pellets — simply blend with your PP resin at 0.5–2% loading. No equipment changes. No process disruption. First-time-right results.
The beta-nucleating agent that delivers an exceptional performance boost to PP Homopolymer.
Works best with non-nucleated & non-clarified grades. Do not use with pre-nucleated PP or alpha-nucleating agents.

Push standard PP Homopolymer into territory previously reserved for expensive impact copolymers, POE, and EPDM — at 1–2% SX-514 loading, with no equipment changes.
Conventional routes to tough PP rely on blending copolymers or elastomers, which compromise stiffness, HDT, and cost. SX-514 nucleates the β-phase, delivering toughness and ductility while holding on to the homopolymer's modulus and heat performance.
One additive, one supply chain — upstream extruded sheet stays tougher, and downstream thermoforming opens up deeper draws, more uniform walls, and higher regrind usage.
The β-phase gives the sheet a tougher, more ductile failure mode — exactly what you want when pulling a hot preform over a tool. The result is consistent wall thickness at deeper draws, and scrap that can be reground and reused without losing mechanical performance.
For thick-section industrial parts, SX-514 delivers a rare combination: higher impact and elongation without giving up the stiffness and HDT that make compression-moulded PP useful in the first place.
Large compression-moulded parts fail in a brittle mode when PP is pushed to thick sections. The β-phase morphology SX-514 nucleates keeps crack propagation slow, giving tougher, more forgiving parts — without changing your tool or press.
Compounders use SX-514 to develop grades their customers have been asking for but couldn't get — impact-enhanced PP that keeps stiffness and HDT, in one letdown step.
Build differentiated grades from a commodity PP base. SX-514 lets you offer impact-copolymer-like toughness without the copolymer price, and stacks cleanly with color, flame retardants, and mineral fillers.
