Ensuring Flawless Rubber Products Through Precise Cooling:
Mixing & Compounding:
During initial stages, raw rubber materials are blended with various additives at precisely controlled temperatures. Airtech's chilled water systems typically maintain temperatures between 30°C and 60°C depending on the specific rubber compound being formulated. This controlled environment ensures proper mixing and prevents premature curing of the rubber.
Internal Mixers & Banbury Mixers:
These high-shear mixers generate significant heat during rubber compounding. Airtech's industrial chillers provide a consistent coolant flow to maintain optimal mixing temperatures and prevent thermal degradation of the rubber compound.
Calendering:
Calendering involves repeatedly passing uncured rubber through heated rollers to achieve the desired thickness and uniformity. Airtech's water chillers provide a cooling medium for the calendering rolls, typically ranging from 50°C to 80°C. This controlled cooling prevents premature vulcanization and ensures consistent product thickness.
Extrusion:
Similar to plastics extrusion, rubber extrusion involves forcing uncured rubber through a die to create continuous profiles. Airtech's water chillers maintain a consistent coolant flow for the die and calibrating bath, typically ranging from 20°C to 60°C depending on the specific rubber compound. Precise temperature control ensures the extruded rubber cools and solidifies at a controlled rate, achieving the desired dimensional stability and product properties.
