Introduction to H-ACR, an Ultra-High Molecular Weight Fluid Foaming Regulator 超高分子量流动性发泡调节剂H-ACR产品介绍

一、Core Definition

H-ACR is an acrylate-based ultra-high molecular weight polymer foaming regulator specially developed for PVC foam products. By precisely controlling monomer composition and polymerization process, it achieves the synergistic optimization of fluidity and melt strength, providing an efficient and stable solution for PVC foam processing.

二、Core Advantages: Component Innovation and R&D Breakthroughs

Compared with traditional foaming regulators, H-ACR has two core differentiated advantages:

1. Precise Component Upgrade: On the basis of retaining traditional core monomers such as MMA (methyl methacrylate), it innovatively adds special monomers with better compatibility with PVC resin, improving the fusion degree with PVC substrate at the molecular structure level, and effectively solving product defects caused by high melt strength but poor fluidity and poor compatibility of traditional regulators.

2. In-depth R&D Accumulation: The core R&D team of the company has gone through years of technical exploration and thousands of experimental iterations to finally establish the optimal formula system. During the R&D process, it broke through the technical bottleneck of balancing melt fluidity and strength in the synthesis of ultra-high molecular weight polymers, taking into account processing convenience and product performance stability.

三、 Core Functions and Values

Based on component and structural advantages, H-ACR can achieve three core functions in PVC foam processing:

1. Promote Plasticization Synergy: Accelerate the gelation process of PVC materials, form a uniform and dense three-dimensional network structure, and improve melt homogeneity;

2. Optimize Cell Structure: Significantly improve melt strength, effectively inhibit bubble coalescence and rupture during foaming, endow products with uniform and fine cell morphology, and ensure mechanical properties while reducing product density;

3. Improve Processing Fluidity: Improve the flow characteristics of PVC melt, reduce processing torque, adapt to different types of extrusion equipment, and reduce material loss and equipment wear during processing.

四、Technical Parameters

五、Application Fields

Widely applicable to the production and processing of various PVC foam products such as PVC foam boards, advertising boards, foam profiles, foam shoe materials, and wood-plastic composite microcellular foam materials. It can be adapted to various process types such as free foaming and skinning foaming.

六、 Significance of Product Development

1. Value in Solving Industry Pain Points: The current PVC foam product industry is facing multiple challenges, such as uneven product surface and uneven cell distribution caused by unbalanced melt fluidity and strength in traditional processing, as well as low production efficiency and high material loss rate (the loss rate of some enterprises can reach 8%-12%) caused by poor adaptability of different equipment. Through the synergistic optimization of fluidity and melt strength, H-ACR can reduce the product defect rate to below 3% and control the material loss rate within 5%.

2. Significance of Product Performance Upgrade: In the application scenarios of PVC foam products, performance requirements are becoming increasingly strict. For example, PVC foam boards for construction need to balance lightweight (low density) and impact resistance, advertising boards need to have good surface flatness and printing adaptability, and foam shoe materials need to meet the balance of softness and wear resistance. By optimizing the cell structure, H-ACR can reduce the product density by 10%-15%, increase the impact strength by 8%-12%, reduce the surface roughness by more than 20%, and does not affect the subsequent secondary processing performance such as printing and film covering, helping downstream enterprises develop high-value-added products that are more in line with market demand and enhance product market competitiveness.

3. Value of Green and Environmental Protection Development: With the tightening of environmental protection policies and the demand for green transformation of the industry, the demand for low-energy-consumption and low-emission additives in the PVC processing field is increasing. H-ACR can reduce the melt processing temperature by 5-10℃ during processing, reducing energy consumption in the production process; at the same time, its high compatibility with PVC resin can reduce additive migration, reduce the risk of harmful substance release during product use, meet relevant environmental protection standards, help enterprises achieve green production, respond to the national "dual carbon" policy, and promote the sustainable development of the PVC foam industry.

七、Quality Control

1. Batch Inspection System: Each batch of H-ACR products must undergo strict inspection. The inspection items include core technical parameters such as intrinsic viscosity, bulk density, volatile matter, and particle size (pass rate through 40-mesh standard sieve). Inspection samples are randomly selected from each batch of products, and the number of samples selected per batch is not less than 3 to ensure the representativeness of the inspection results.

2. Qualification Criteria: Each batch of products must meet all technical parameter indicators (intrinsic viscosity 16.0±0.3ml/g, bulk density 0.4±0.05g/cm³, volatile matter ≤1.2%, particle size pass rate ≥99.5%), and the deviation of inspection results is within the allowable range before a qualified factory inspection report can be issued; if one of the indicators is unqualified, re-sampling inspection is required. If the secondary inspection is still unqualified, the batch of products is judged as unqualified and prohibited from leaving the factory.

八、After-sales Service and Technical Support

（一）After-sales Service Guarantee

Handling of Product Quality Issues: If a customer finds that the product quality does not meet the standards (such as caking, key indicators not meeting requirements) during the use of H-ACR products, the company will respond within 24 hours after receiving the feedback and arrange technical personnel to verify the situation at the customer's site within 48 hours. If it is confirmed to be a product quality issue, the company will handle the return and exchange for the customer within 7 working days and bear the relevant logistics costs; if the customer's production loss is caused by product quality issues, the company will negotiate a compensation plan with the customer according to the actual situation to protect the legitimate rights and interests of the customer.

（二）Technical Support Services

1. On-site Technical Guidance: For customers using H-ACR for the first time, or when customers adjust production processes or develop new products, the company will send technical engineers to the customer's production site to provide guidance services free of charge, assist customers in solving technical problems encountered during trial production, and ensure the smooth commissioning of the product.

2. Customized Solutions: For customers' special needs (such as the development of PVC foam products with specific performance, adaptation of special processing equipment, etc.), the company's R&D team will conduct in-depth communication with customers to understand product application scenarios, performance index requirements and production process parameters. Through formula adjustment, process optimization and other methods, it will provide customers with customized technical solutions, and conduct small-batch test verification to ensure the feasibility of the plan before promoting it to mass production, helping customers achieve product innovation and process upgrading.
