Product Description

 
Product Description
Hunthumber CT3718  resins are acid-anhydride-modified polyolefin resins. They are available in pellet form for use in the conventional extrusion and coextrusion equipment designed to process polyethylene (PE) resins. 

Hunthumber™ CT3718 is a grade with a higher level of anhydride modification, primarily intended for use as a component in blends with other polyolefin resins. It is not suitable for extrusion in its pure form during typical extrusion or coextrusion processes.

Product Parameters
Composition Ultra 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 Hunthumber CT3718 resin exhibits physical properties similar to linear low-density polyethylene (LLDPE) with similar density and melt index. Use of this adhesive resin in coextruded PE/barrier structures offers improved thermal resistance over that of ethylene vinyl acetate-based adhesive resins.
Applications Hunthumber CT3718 resin adheres to a variety of materials. It is most often used to adhere to EVOH, polyamide, PE, and ethylene copolymers.
Hunthumber CT3718 resin can be utilized in the following co-extrusion processes:
  1. blown film
  2. cast film/sheet
  3. blow molding
  4. sheet and tubing

Adhesive Evaluation

The performance of any adhesive resin should be evaluated within the context of the application. The adhesive is designed to bond materials that would not ordinarily adhere to each other. In most cases, peel strength is used as a measure of performance. Although this is a convenient test, peel strength is affected not only by adhesion but also by factors such as peel angle, separation rate, temperature, and tensile and modulus properties of the materials, and often by the time elapsed since the formation of the bond. Post-treatment of the multi-layer structure, such as heat sealing, thermoforming, or orientation, can also affect peel strength.

General
Processing Information
In coextrusions with thermally sensitive resins such as EVOH or EVA, we suggest that the maximum melt temperature be limited to 235°C (455°F) to guard against overheating the EVOH or EVA. If adhesion results are adequate, we suggest evaluating even lower melt temperatures such as 210 - 220°C (410 - 428°F).

For coextrusion with polyamides or other thermally stable resins, the melt temperature can be higher. We suggest a maximum melt temperature of 260°C (500°F). This should provide acceptable bond strengths and film quality under almost all coextrusion conditions. If adhesion results are adequate, melt temperatures can be lowered. While it is possible to extrude Hunthumber™ CT3718 resins as high as 300°C (572°F), such high extrusion temperatures, particularly when coupled with long residence times, may result in some film imperfections. In certain streamlined extrusion operations, where residence times are short, it may be possible to use temperatures higher than 260°C (500°F).

In the event of a brief interruption during the extrusion processing, it is essential to operate the screw at a low speed. Prior to extended shutdowns, it is necessary to thoroughly purge the Hunthumber™ CT3718 resins from the extruder using polyethylene. During purging, the processing temperature should be maintained without change.


 
Storage Condition Hunthumber CT3718 resins should be stored under dry and cool conditions. Improper storage conditions may cause degradation and have consequences on physical properties of the product.
