Frequently Asked Questions (FAQ)

Q1: What is Bubble Modifier ACR-530?
A: ACR-530 is a professional acrylic-based bubble modifier, specially developed to enhance PVC melt viscoelasticity and achieve precise control of the cell structure in various low-to-medium expansion ratio foamed products.

Q2: What core technical performance can ACR-530 deliver?
A: It effectively promotes uniform plasticization of PVC resin, significantly increases melt strength, prevents bubble merging, rupture and collapse, and helps produce foamed products with finer, more uniform cell distribution.

Q3: What typical application scenarios is ACR-530 suitable for?
A: It is widely used in UPVC wood-plastic products, crust foamed building templates, low-density foamed decorative boards, SPC foamed base materials and PVC shoes or sole

Q4: What is the recommended addition dosage of ACR-530 in conventional PVC foaming formulations?
A: For most standard rigid PVC foaming systems, the recommended dosage ranges from 3.5 phr to 6.0 phr, and the specific amount can be flexibly adjusted according to your target foaming ratio and equipment process conditions.

Q5: What are the unique advantages of ACR-530 compared with ordinary foaming regulators?
A: It has a specially optimized molecular weight distribution, which balances plasticization speed and melt strength performance. It can effectively reduce the density of foamed products while maintaining good surface smoothness and low energy consumption characteristics.

Q6: How does ACR-530 perform in compatibility with other foaming-related additives?
A: It shows excellent compatibility with PVC resin, AC/NC compound foaming agents, calcium-zinc stabilizers, internal and external lubricants, and other common additives, and will not cause dispersion problems or abnormal foaming under normal processing conditions.

Q7: What are the key technical specifications of ACR-530?
A: It appears as a white free-flowing powder, with intrinsic viscosity of 11.0–15.0, apparent density 0.30–0.50 g/cm³, volatile content ≤1.5%, and 30-mesh sieve residue ≤2.0%, meeting the general industrial standards for PVC foaming processing.
