To address stringing on PVC dot-coated gloves, focus on three key areas: material, process, and equipment. Material: Ensure the PVC paste viscosity is optimal. Adjust with plasticizers or thickeners to reduce excessive flow that causes strings. Process: Precisely control oven curing temperature and time. Incomplete gelation due to low temperature or short time is a primary cause. Optimize the dip-coating speed and withdrawal angle for a cleaner release from the mold. Equipment: Regularly clean a

To regain mechanical strength without fully sacrificing low-temperature flexibility, consider these integrated adjustments: Partial Replacement: Substitute a portion of the primary plasticizer with a polymeric or secondary plasticizer (e.g., DOTP, DINCH). These often offer better permanence and less softening efficiency. Reinforcement: Incorporate low-loa
