Bynel 4140

За овој производ

BYNEL Series 4100 resins are anhydride-modified, linear low-density polyethylene (LLDPE) resins. All 4100 series resins are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene (PE) resin.

BYNEL 4140 is a grade with a higher level of anhydride modification, and is mainly intended for use as a component in a blend with other polyolefin resins. It is not intended for extrusion in its pure form in typical extrusions or coextrusions.

Composition

• High% By Weight Maleic Anhydride
• Graft levels are defined as:
• Low < 0.2%; Medium 0.2-0.5%; High 0.5-1.0%; Ultra high > 1.0%

Characteristics / Benefits

• Physical properties of BYNEL Series 4100 resins are typical of linear low density polyethylene resins with similar density and melt index values. Use of these adhesive resins in coextruded PE/barrier structures offers improved thermal resistance over that of ethylene vinyl acetate-based adhesive resins.

Applications

• BYNEL 4100 series resins adhere to a variety of materials. They are most often used to adhere to EVOH, polyamide, PE and ethylene copolymers.

Series 4100 resins can be used in coextrusion processes including:

• blown film
• cast film/sheet
• blow molding
• melt and solid phase thermoforming
• sheet and tubing

LLDPE resins are known for their temperature resistance, clarity and toughness.
These physical properties make the 4100 series resins work well in applications such as:

• boil-in-bag structures
• blow molded containers in which drop strength is important
• bag-in-box films
• film where LLDPE is the heat seal layer.
