Polymerization Initiators for Plastic Compounds

Einar® 987 by Palsgaard is a non toxic anti-fouling agent for polyolefins. It is plant-based, food-grade polymerization additive.

• It eliminates static build-up during polymerization and prevents fouling of the reactor wall, thus helping PP and PE producers maintain the cooling efficiency of the reactor.
• It provides high anti-fouling efficiency at low dosage (100-300 ppm) without any negative effects on catalyst mileage, productivity or final polymer performance.
• It has controlled reactor temperature and sustained reactor efficiency that ensures continuous production & consistent product quality. It is ideal drop-in solution for existing dosing systems.
• It is highly applicable for global implementation and eliminates concerns in sensitive applications such as medical devices.
• It is safe to use and contains no health hazards.
• The product offers a drop in regulatory compliant solution to replace incumbent ethoxylated amines and can also be used as a more efficient alternative to sorbitan monooleates.
• It is manufactured from vegetable oils in accordance with EU regulations and in compliance with Good Manufacturing Practice (GMP, EC no 2023/2006).
• It has worldwide food-contact compliance such as EU, USA, Mercusur and China.
• Einar® 987 has a shelf life of minimum 12 months.

NYRIM® P1-30 Prepolymer by Brüggemann is a high molecular weight, viscous elastomeric polymeric liquid activator in the anionic polymerization of AP-NYLON® Caprolactam, along with the NYRIM®C1-Catalyst. This system enables the production of homogeneous cast parts of a reproducible high quality (fast demolding after less than 10 minutes) and low casting temperatures (melt: 95-105°C, mold: 140-150°C). It is recommended for two component casting equipment and cast polyamide. It is suitable for large, low-tension semi-finished products, such as bars, tubes, and plates, to complex, often thick-walled molded parts that cannot be manufactured through injection molding or extrusion. The product is used in rough and tough applications. The shelf life of the product is at least 24 months under (dry, 25°C) conditions. Recommended dosage level of NYRIM® P1-30 Prepolymer is 15-44%.

NYRIM® P1-20A Prepolymer by Brüggemann is a high molecular weight, viscous elastomeric polymeric liquid activator in the anionic polymerization of AP-NYLON® Caprolactam, along with the NYRIM®C1-Catalyst. It is recommended for two component casting equipment and cast polyamide. This system enables the production of homogeneous cast parts of a reproducible high quality (fast demolding after less than 10 minutes) and low casting temperatures (melt: 95-105°C, mold: 140-150°C). It is suitable for large, low-tension semi-finished products, such as bars, tubes, and plates, to complex, often thick-walled molded parts that cannot be manufactured through injection molding or extrusion. The product is used in rough and tough applications. The shelf life of the product is at least 24 months under (dry, 25°C) conditions. Recommended dosage level of NYRIM® P1-20A Prepolymer is 11-22%.

BRUGGOLEN® C235 by Brüggemann is N-ethylpyrrolidon-free liquid activator for AP-NYLON® casting along with a catalyst BRUGGOLEN® C10. It enables efficient polymerization. It provides prolonged open time and toughness. It offers cost-effective system for moldings. The dosage level of the product is 0.5-1.5%. BRUGGOLEN® C235 is designed for AP-NYLON® cast polyamides. The shelf life is atleast 12 months.

Perkadox® AMBN-GR BY Nouryon is an initiator for bulk, solution and suspension. It is suitable for styrene, vinyl chloride, vinylidene, acrylonitrile, acrylates and methacrylates. Perkadox® AMBN-GR generates less aggressive C radicals compared to peroxide initiators, avoiding excessive grafting and form low-molecular weight resins. The shelf life of this product is 3 months.

LPO by Changzhou Joho Chemical is used for the (co)polymerization of vinyl chloride, vinylidene chloride, acrylates, and methacrylates, and is mainly applied in the suspension polymerization of vinyl chloride. It is also used for the polymerization of vinylidene chloride.

CHP by Changzhou Joho Chemical is a polymerization initiator, curing agent for resins, and crosslinking agent for elastomers and thermoplastics.

• It may be activated by organic-soluble or water-soluble reducing agents, or by metal compounds to achieve polymerization at room temperature or lower.
• It may be used for various polymerization reactions including emulsion, solution, and bulk polymerizations.
• It has a shelf life of 3 months.

High Purity TBEC by Changzhou Joho Chemical used as an initiator for the (co)polymerization of ethylene, styrene, butadiene, acrylate, and methyl acrylate.

TBPB by Changzhou Joho Chemical is a polymerization initiator, crosslinking agent, and curing agent. It is suitable for high-pressure ethylene polymerization in autoclave and tubular processes, for polymerization of low-density polyethylene, polystyrene, and acrylic resins. It is used for crosslinking of EPDM, silicone rubber, and specialty rubber products, and for curing hot-press molding formulations of unsaturated polyester resins, and can crosslink EPDM rubber compounds at ambient temperature within weeks.

DTAP by Changzhou Joho Chemical is an excellent initiator for LDPE and acrylic resins and performs efficiently under high-pressure conditions. It is used as an initiator for solution (co)polymerization of acrylates and methacrylates and for high-pressure ethylene polymerization in autoclave and tubular processes.
