CP130
A Thermoplastic Multipolyamide
The thermoplastic polyamide for tough, high elongation, soluble and adhesive or flexibiliser applications.
CP 130 is a multipolyamide product from the Chennai Polychemicals Pvt. Ltd., manufacturer of bulk drugs since 1990 which has clientele across India.CP 130 is a thermoplastic multipolyamide of lower melting range which exhibits excellent toughness, higher elongation and easy solubility in alcoholic solvents and their blends.
This multipolymer thermoplastic polyamide also has a special property of crosslinking with a thermosetting resin which makes it suitable as ahot melt adhesive, solvent based adhesive or merely as a flexibiliser that finds a variety of end uses.
CP 130 is supplied in 25 kg HDPE lined kraft paper bags and in the form of clear, uniform chips.It is tough in dry condition but with continuous exposure to atmosphere makes it soft and flexibledue to moisture absorption. Excellent toughness, higher elongation and easy solubility in alcoholic solvents and their blends make it useful for wide variety such as Hot-Melt Adhesives in Nylon Laminated Transmission Belts, Tapes, etc., in Footwear Industry for different component joining, in Textile Industry for Sewing Thread Bonding, PVC Cloth Coating, Fabric Dip Coating, Leather Coating and in Electrical industry for Cable and Wire Sheathing.
Physical Properties
The product is a mutipolymer thermoplastic polyamide, available as clear uniform 2mm chips with a bulk density of 1.11g/cc. Water Absorption at max. 23°C is in the range of 10-12% and Moisture regains is in the range of 2.5-3.5% after 24 hrs (ASTM test method D570). The usual polyamide viscosity number measured in 95% sulfuricacid, 0.5 g/100ml is in the range of 2.5-2.7. Density determined ASTM test method D 792 is 1.11g/cc. The product melts at the range of 160-170°C (ASTM test method D2117) and the glass transition temperature of the dry material is about 40°C.
Mechanical Properties
CP130 is mainly applied assolution on leather, nylon and or substrate. The properties of the adhesive solution is directly proportional to the adhesive solution components ratio, making process, base material and application technique. The tensile strength is 49.7 Mpa and Elongation is 300% under the test method of ASTM D 638. The impact strength is 4.9 Kg cm/cm under the test method of ASTM D 256A.
Storage
CP 130 thermoplastic polyamide can absorb moisture from the atmosphere and should be carefully packed or sealed and stored in dry conditions without exposure to moisture. The product can be stored successfully atleast for a year provided the precautionary measures are taken.
Preparation of Adhesive Coating
Adhesive solutions of CP 130 thermoplastic polyamide are generally prepared both at room temperature and may need to warm up to 25-40mixing of the solvent components. A variety of alcoholic solvents and their blends can be used. The examples are
- 80% Methanol + 20% Water
- 70% Methanol + 20% Benzene + 10% Water
- 70% Methanol + 20% Methylene Dichloride + 10% Water
- 100% Methanol
The general guideline for preparing the Adhesive Coating involves adding 10-20% of CP 130 to any one of the solvent mixture listed above (A,B,C or D) with stirring in a high speed Agitator or Tumbler Mixer. The mixture is stirred for 2-6 hours until the solution becomes uniform and ready for application.kl;moo
