Polyamide and polyimide
Our dimer diol can be used in polyamide or COPA:
Pripol™ bio-based* dimer fatty acids and dimer diols
This product range has been designed to enhance performance properties such as improved flexibility, excellent water barrier protection, low and stable color, enhanced melt flow and improved multi-substrate adhesion, as well as carbon footprint improvements and in-use sustainability benefits.
Pripol™ dimer fatty acids and dimer diols are especially useful in highly demanding applications such as transportation, electronics, sportswear and food packaging. Dimer modification can also reduce polymer density, perfect for light-weight applications.
Priplast™ polyester polyols offer unique proprieties to copolyamide (COPA) elastomers. They range from soft to semi-rigid products offering good thermo-oxidative stability and hydrolysis resistance and outperform conventional polyols.
The benefits of these polyester polyols include water resistance, a wide window of application temperatures and enhanced melt flow.
These materials are high-end block copolymers and find use in heavy-duty sports, automotive, electronic cabling and tubing applications.
Priamine™ provides polyamides with flexibility, reduced melt viscosity for enhanced mold flow and improved adhesion. The low moisture absorption reduces strength variations and brings improved dimensional stability. Priamine™ can also be built in as a tough, segmented block-copolymer. Using it in this way means that the rigidity (high Tg) of the hard matrix can be maintained.
Excellent Mechanical Properties in Polyamide Plastics: Nylon 6 ‘modified’ with C44 Dimer versus C36 Dimer
Modifying the Nylon 6 with dimer gives Nylon 12- like properties of high elongation with good tensile strength.
Priamine™ 1075 dimer diamine: this product has been selected for use in high performance polyimides due to its high purity, high difunctionality and low color. This low viscosity material allows producers to reduce the use of expensive solvents during processing.
High performance, flexible solutions
Priamine™ 1075 is a low viscosity, high purity dimer diamine building block is designed for use in high molecular weight polyamides and high-performance polyimides in adhesives, sealants, elastomers and engineering plastics.
It gives formulators freedom to adjust the melting point, allowing for higher temperature exposure of the end product without compromise on performance.
Priamine™ 1075 dimer diamine is an ISCC PLUS certified product. The vegetable oil-based content comes from ISCC certified sources (mass balance).
Pripol™ 1004 is a building block that enhances high performance engineering plastic properties for severe application areas.
This bio-based building block combines flexibility and toughness and offers extremely high moisture resistance making it suitable for moisture sensitive applications in electronics. It has very low color properties meeting ultra-transparency properties for film applications.
