Residence Time: Screw should not be left idle for more than 3-4 minutes with melt in the barrel. Excess residence will be visible as black carbon specs in the melt.
Regrind Level: Typically, up to 25% is recommended but higher levels are possible with little or no effect on flow and finish.
Drying Temperature: Although Nylene resins are packaged and delivered in a low moisture state, it is good material handling practice to use a hopper dryer to maintain dryness. Should pre-drying be necessary, use settings of 180 °F (82.2°C) air at dew point of -40 at a rate of 1 cu. ft. / hour per pound of resin and a residence time of 2-4 hours.
Cooling and Sizing: While both air and water can be used as the cooling medium, air is preferred. The use of air allows additional time for sizing and reduces residual stress. This aids in reducing warpage, especially in profiles with varying wall sections. If water is used, heat the first section to above 100 °F (38°C) to reduce quenching and residual stress.
Die Design: Draw down of 30% is typical for all dimensions except wall thickness.
Land length: should be around 10x wall thickness.
High viscosity nylon 6 designed for the extrusion of blown film (both mono-layer and multi-layer film structures). Suitable for profile extrusion such as tubing, shapes, etc. Nylene 615SA has superior grease resistance, toughness, resistance to abrasion, and does not absorb food odors. Nylene films can be drawn to provide pockets for many food shapes. Good oxygen and flavor barrier to increase shelf life Offers chemical and heat resistance for hot filling wide range of food and chemicals
Read moreNylene 764B is a heat stabilized, high impact modified nylon suitable for both blow-molding and extrusion. In addition to heat stabilization to prevent thermal degradation, parts molded from Nylene 764B have excellent impact strength right out of the mold without post conditioning. Outstanding features of Nylene 764B include high strength and high cold temperature impact. Cylinder temperatures should be in the 435 – 525ºF (224 – 274 ºC) range. Excellent melt strength to support large parisons
Read moreVery high viscosity extrusion resin having an ASTM relative viscosity of 800. Particularly recommended for the extrusion of thick slab, large rod stock, and large complex profiles. Optimum processing conditions should permit for a melt temperature of 550 – 575°F (289 – 301°C) at the die. Properties promote dimensional control for extrusion of pipe, tubing, film, and sheet.
Read moreNylon 6, high viscosity, extrusion grade recommended for practically all types of extrusion including profile, film, and extrusion coating Can also be used for blow molding applications Optimum processing conditions should permit for a melt temperature of 550 – 575°F (289 – 301°C) at the die. Especially recommended for flexible packaging where as a film or coating it is used for the outside layer in multi-ply film constructions
