Ascend’s Portfolio of PA66 Compounding Feedstock Resins
Feedstock grades are formulated individually to obtain the optimal balance between the desired mixing level and integration of additives to PA66 backbone without sacrificing the flow characteristics and mechanical properties needed for the final application.
Lower-viscosity resins (21LS and 21ZLV) enable mixing shearsensitive materials and high-percent filler concentration where distributive mixing is essential to the final product performance.
The compounded product will maintain its high flow and performance needed for the application.
Medium- and high-viscosity grades (21MST, 21Z-NT01A2, 21Z, 50BW, 21FS-R and 52BW-MS) provide dispersive mixing without causing degradation of PA66. The new 21Z-NT01A2 grade is unique in its class with its high concentration of amine end groups, which is proven to be an advantage for moisture sensitive formulations. Also, the new 21MST grade provides excellent melt viscosity stability against moisture throughout the extrusion process.
Ascend’s Portfolio of PA66/6 Compounding Feedstock Resins
Ascend produces medium-viscosity PA66/6 random copolymers (88X, 85XFS and 86XFS) for compounds containing heat-sensitive additives and end-use applications that require good surface finish. These copolymer resins have melt temperatures varying from 235° to 255° C based on the comonomer concentration.
These copolymers are specifically designed to be used with FR packages and high mineral loadings.
- Vydyne® 21ZLV
Vydyne® 21ZLV is a lower-viscosity, general-purpose PA66 resin. It is available in natural and designed for extrusion-compounding applications. Vydyne 21ZLV is the feedstock of choice for highly filled TM products and reactive-compounding applications.
- Vydyne® 50BW/50BWFS
Vydyne® 50BW and 50BWFS are general-purpose PA66 resins. Offered in natural and designed for extrusion-compounding applications, this product is available at two moisture levels: 0.2% (max) as 50BW and 0.5% (max) as 50BWFS.
- Vydyne® 21Z
Vydyne® 21Z is a general-purpose PA66 resin. It is available in natural and designed for extrusion-compounding applications. This resin offers a well balanced combination of engineering properties characterized by high strength, rigidity, good toughness, high melt point, good surface lubricity and abrasion resistance.
- Vydyne® 21FSR
Vydyne® 21FSR is a higher-viscosity, general-purpose PA66 resin. It is available in natural and designed for extrusion-compounding applications. This resin offers a well balanced combination of engineering properties characterized by high strength, rigidity, good toughness, high melt point, good surface lubricity and abrasion resistance.
- Vydyne® 63A
Vydyne® 63A is a medium-viscosity resin used for injection-molding and extrusion-compounding. It is desirable to include this neat resin in a formulation in which the melt strength of the final product is critical for the application. Vydyne® 63A exhibits good initial color and it has a moisture level below 0.1%. This product offers high strength, rigidity and toughness over a broad range of demanding applications. Resistance of Vydyne® 63A to heat, oil and wear is typical of PA66 neat resins.
- Vydyne® 85XFS
Vydyne® 85XFS maintains the chemical resistance typical of PA66/6 to many chemicals, machine and motor oils, solvents and gasoline.
