A stabilizer affects PVC thermal stability, color, processing window, and line stability. For processors, product specifications are not the only important factor. It is equally important how the stabilizer performs in real production: during extrusion, calendering, molding, plastisol processing, and other processes.
RIPA, Reagens India Polymer Additives, is an international manufacturer of PVC stabilizers. The company was established in 2019 as a joint project between the European manufacturer Reagens and the Indian company Indofil. The RIPA plant is located in Dahej, Gujarat, with a planned capacity of 60,000 tons of additives per year.
For Revada Plastic, the Reagens stabilizer business has a long history. We have been working with Reagens stabilizers since 2002 and have achieved leading positions in the Russian PVC stabilizer market over this period. Cooperation with RIPA became a continuation of this work, as RIPA applies Reagens technological principles and standards in stabilizer production.
RIPA and Reagens Technical Expertise
RIPA operates according to Reagens production standards: incoming raw material control, comprehensive laboratory testing of finished products, batch-to-batch consistency, and technical support for customers. For PVC product manufacturing, this is critical because even minor deviations in a stabilizer can change the product shade, reduce thermal stability, affect surface appearance, or require formulation adjustments.
RIPA specialists have visited Russian production sites many times, studying equipment, formulations, and processing conditions. As a result, the company understands the specifics of the Russian PVC market: requirements for stability, color, heat resistance, light resistance, transparency, lubricant balance, and thermal stability on industrial lines.
Many Revada Plastic customers have also taken part in joint visits to the RIPA plant. They were able to assess the production facility, laboratory control, and the expertise of the company specialists themselves. This direct contact helps move faster from formulation discussion to solution search, industrial trials, and implementation of new developments.
Stabilizers for Different PVC Processing Tasks
RIPA produces different types of PVC stabilizer systems: lead-based, calcium-zinc, barium-zinc, calcium-organic, and tin stabilizers. This makes it possible to select solutions for rigid and plasticized PVC, transparent and opaque products for outdoor and indoor use, cable compounds, profiles, films, sheets, and technical products.
Because there is no single universal stabilizer for all PVC applications, the formulation depends on the product type, equipment, line speed, and processing method, as well as requirements for color, transparency, light resistance, heat resistance, and cost efficiency.
For dark-colored products, light resistance, heat resistance, shade stability, and the ability to achieve the required stable color with a minimum pigment dosage are especially important. For transparent products, initial color and the absence of haze are critical. For extruded profiles, a smooth surface, stable extrusion, and consistent color across the upper and lower parts of the product are important.
In all formulations, a properly selected stabilizer package helps reduce rejects, simplify the compound composition, and optimize dosage without losing the required processing result.
That is why RIPA stabilizers are selected and fine-tuned for a wide range of customer tasks.
RIPA and Revada Plastic
Revada Plastic has been working with RIPA since 2021. After successful trials with Russian customers, RIPA stabilizers became an important part of the company product portfolio and the basis of the Reapak product line.
The partnership between Revada Plastic and RIPA enables customers to receive reliable PVC stabilizers, technical support during implementation, and the ability to adjust formulations for real production tasks. We help select a stabilizer system for a specific formulation, conduct trials, analyze processing issues, and adapt the solution to the conditions of a particular line.
