Who is Donglin
Shandong Donglin New Materials is one of the world’s largest producers of additives for the processing of PVC and other polymers. The company produces acrylic modifiers for PVC, MBS modifiers for transparent products, complex impact strength modifiers and recyclability modifiers, as well as chlorinated polyethylene CPE. The combined capacity exceeds 200,000 tons per year, making Donglin the largest exporter of acrylic modifiers in China and a prominent player in the global PVC additive market.
For Revada Plastic, Donglin is a strategic manufacturing and technology partner. In the Russian and CIS markets, the joint line of acrylic modifiers is marketed under the Revamod brand and is used in PVC window profiles, sheets, pipes, transparent products, and other rigid compositions. The primary objective of the Revamod line is to ensure high impact strength and stable processability on industrial equipment.
Production and Laboratories: Focus on Reproducibility
Donglin’s production facility includes raw material inspection laboratories, finished product analysis laboratories, and a well-developed research center. Internal standards establish tight tolerances for particle size, butyl acrylate content, bulk density, and volatile content. This approach ensures the stability of Revamod modifiers from batch to batch and the predictable behavior of PVC compositions during processing.
For processors, this means reproducible formulations, consistent melt viscosity profiles, and a lack of technological surprises when switching between suppliers. The stability of these parameters is crucial for high-speed PVC extrusion lines.
Testing Facility: Validation in Real PVC Processing
Donglin’s unique advantage lies in its own PVC processing testing facility equipped with various extrusion lines. Revamod’s impact strength modifiers and processability modifiers are tested not only in the laboratory but also in real formulations for window profiles, pipes, and sheets. This allows for pre-evaluation of the additives’ compatibility with specific equipment, dosage selection, and prediction of material behavior during production.
The comprehensive Revamod modifiers combine the functions of enhancing impact strength and improving processability, expanding the processing window and facilitating formulation adjustments. This approach is particularly important for CIS enterprises that utilize various types of extruders and a wide range of processing modes.
Results in Products: Impact Strength, Seams, and Transparency
The use of Revamod modifiers allows for the production of products with high impact strength, even at negative temperatures, which is critical for building and facade materials. They contribute to the formation of strong welded joints in window profiles, reduce the risk of microcracks, and increase the frost resistance of PVC products. The use of CPE and combined systems further enhances the resistance of products to mechanical stress.
MBS modifiers from Revamod are used for transparent PVC products and ensure the absence of cloudiness, flow bands, and structural defects. In terms of performance, Revamod acrylic modifiers are comparable to European counterparts in terms of impact strength, stability after climatic testing, and compatibility with standard formulations for the production of PVC products for various purposes.
Why are Donglin and Revamod important for the CIS market?
For PVC processors in the CIS region, three key factors remain important: quality stability, predictable supply, and technical support. Donglin’s large-scale production reduces the risk of additive shortages and ensures the stability of supply chains. The narrow specifications guarantee the reproducibility of properties, while the extensive R&D base allows for the customization of products to meet the specific requirements of production facilities.
Revada Plastic provides local technological support, the selection of Revamod grades based on the customer’s equipment, and the support of industrial tests. As part of the collaboration, it is possible to develop modifiers tailored to specific project requirements, which is particularly important for complex PVC formulations.
Summary
The partnership between Donglin and Revada Plastic combines large-scale production of a wide range of modifiers for PVC and practical expertise in the formulation of PVC compositions. As a result, processors receive stable impact strength modifiers, effective recyclability modifiers, comprehensive solutions for PVC, and technological support for implementation. This approach reduces production risks, improves the repeatability of product quality, and makes technological processes more manageable.
