For PVC manufacturers striving for consistent product quality and optimal processing, understanding the technical specifications of their raw materials is non-negotiable. NINGBO INNO PHARMCHEM CO.,LTD. offers ACR801, a premium acrylic impact modifier, and provides a transparent look at its detailed technical profile. This information is vital for formulators and production engineers to effectively integrate ACR801 into their PVC compounds and achieve the desired performance characteristics in final products like pipes, profiles, and boards.

The appearance of ACR801 is described as a white powder. This physical form is standard for many polymer additives and allows for easy handling and incorporation into dry blends or melt compounding processes. The bulk density, typically around 0.40-0.50 g/cm³, is an important factor for volumetric feeding and ensuring consistent loading in the production line. Variations in bulk density can affect the dosage accuracy, so consistent quality from the supplier is key. When considering the purchase of ACR801, manufacturers should ensure that these basic physical properties meet their operational needs.

One of the most critical technical parameters for any polymer modifier is its intrinsic viscosity (η). For ACR801, a typical range is between 3.0 to 5.0, measured under specific conditions (e.g., at 25°C). Intrinsic viscosity is a measure of a polymer's molecular weight and its contribution to the overall melt strength and rheological behavior of the PVC compound. A higher intrinsic viscosity generally indicates a higher molecular weight, which can translate to better impact resistance and melt strength. Understanding this specification helps manufacturers predict how ACR801 will perform in their specific PVC formulations and processing conditions.

Volatile content is another important indicator of product purity and stability. A low volatile content, typically less than 1.5% for ACR801, signifies that the material is well-dried and free from excessive moisture or residual solvents, which could negatively impact processing or final product properties. Similarly, screenings content (residue after sieving) provides insight into the fineness and uniformity of the powder. A low screenings content (e.g., ≤ 2.0% for a 30-mesh sieve) ensures that the modifier disperses evenly, preventing processing issues or surface defects in the finished PVC product.

NINGBO INNO PHARMCHEM CO.,LTD. provides these detailed technical specifications to empower its customers. By understanding parameters like intrinsic viscosity, volatile content, and particle size distribution, manufacturers can fine-tune their formulations for optimal impact modification, improved melt fluidity, and excellent surface finish. This technical transparency is a cornerstone of NINGBO INNO PHARMCHEM CO.,LTD.'s commitment to delivering high-performance solutions and supporting their clients in achieving manufacturing excellence.
