KAPVL has also diversified into International Quality Rubber Chemical Dispersions and Specialty Latices. KAPVL produces a wide range of dispersions both Single and Composite. The specialty latices include No Ammonia Latex. Ultra-Low Ammonia Latex, No Nitrosamine Latex, Condom Grade Homogenised Latex (CGHL), and Ultra-Low Protein Latex.

Prevulcanised Latex Rubber

KA Prevultex Grades are accepted in the market for their shelf life, online process life, consistency, low toxicity, lesser wastage, etc. It has end-use applications in condoms, foley catheters, MEC, baby teats, foam toys, carpet backings, bladder, balloons, cast articles, adhesives, and gloves.

KA Prevultex MM-C is used by all major Foley Catheter manufacturers. We have the LA MM grade which is a Low Ammonia Grade that is used by the MEC manufacturers in India and abroad. These grades have been widely accepted for their low toxicity, low residual chemicals, and acceptable protein levels. KA Prevultex HMM 10 is widely accepted by condom manufacturers for its consistency, low wastage levels, and shelf life.

The KA Prevultex LM balloon grades have been a favorite of the balloon industry, LM B being the color-specific grades and LM BN being the general grade. KA Prevultex CBT caters to the carpet-backing industry. KA Prevultex MM B is used by the sports goods industry in making bladders. We also have the LM-M grade used for lamination. The grade KA Prevultex ADH is used as an adhesive in the tennis ball industry. The base grade KA Prevultex MM is used by the toy industry, especially for foam toys.

Rubber Chemical Dispersions / Prevulcanised Natural Latex Rubber

KA Prevulcanised Latex Pvt. Ltd manufactures a range of Single and Composite dispersions under the brand KA Dispersions.

These dispersions are designed to work in synergy with natural rubber and are produced under stringent conditions.

Our dispersions have the advantage of

A faster rate of cross-linking
Less chemical dosagge
Less chemical sedimentation and wastage
Uniform chemical distribution
Intimate mixing of rubber particles and chemical
Better aged properties
Unlike the normal chemical dispersions, KA Dispersion is well dispersed in the aqueous phase minimizing sedimentation and valuable chemical wastage during the compounding and manufacturing process. KA Dispersion allows reduction of chemical dosage leading to cost-saving to a formulator.

KA Dispersion also offers customized dispersions made using our sophisticated in-house technical capability.

All dispersions are available in 5kg, 10kg, 25kg, 50kg, 100kg and 200kg HDPE container

Speciality Latex Rubber

KA Prevulcanised Latex produces a range of Specialty Latices.

Ultra Low Protein Latex (ULPL)
Ultra low Ammonia CL 60
No Ammonia CL 60
No Nitrosamine CL 60
Centrifuged Homogenized Latex (CHL)

The very range of specialty lattices shows that at KAPVL we are working for a green environment.

Their Ultra-Low protein Latex uses green chemistry that virtually eliminates antigenic protein, lutoids, and other organic particles resulting in a cleaner and purer natural rubber latex. The benefits are lesser leaching to extract proteins, reduced water consumption, lower energy and sewage expenses, easy integration, requires no process change or capital expenses. It has a 100% green footprint.

KAPVL is the first Company to commercially manufacture ultra-low ammonia and No ammonia CL 60. The ultra-low ammonia latex is specifically designed for the foam industry. – No de-ammoniation, no loss of rubber, and no mess with ammonia. Say No to Ammonia, use our No ammonia CL 60. As is well known, for over 75 years ammonia has been the primary preservative used in natural rubber. Its strong odour, irritation to the eyes, nose, and skin, makes its use a recurring problem. Our R&D has worked for years to find an ideal replacement for ammonia.

Use of No ammonia CL 60 makes your working environment a much safer and pleasant place for you and your customer. No ammonia is used at any stage from tree to finished product. If you are using NR Latex for the production of dipped goods, adhesives, or coatings our No ammonia CL 60 may well be the answer to your problems of odour, health and safety issues.

We also have No ammonia No nitrosamine CL 60, Centrifuged Homogenized Latex(CHL)
