四、产品主要功能 / Main Functions
1. 提高熔体强度 / Improve Melt Strength
增强 PVC 熔融体的拉伸强度与粘弹性，支撑发泡气体膨胀，减少塌泡、破泡、收缩变形。
It enhances the tensile strength and viscoelasticity of PVC melt, supports foam expansion, and reduces foam collapse, cell rupture and shrinkage.
2. 细化泡孔结构 / Refine Cell Structure
稳定成核体系，促进泡孔细密、均匀、独立，降低吸水率，提高板材平整度。
It stabilizes cell nucleation, promotes fine, uniform and closed cells, reduces water absorption and improves surface smoothness.
3. 调节塑化速率 / Control Plasticization Rate
平衡物料塑化速度，避免过塑、欠塑，改善板面波纹、橘皮、麻点等缺陷。
It balances plasticization rate, avoids over-plasticization or under-plasticization, and improves waviness, orange peel and pitting.
4. 提升填充容纳性 / Improve Filler Tolerance
适配高钙粉填充体系，在高填充条件下仍保持较好发泡稳定性。
It is suitable for high calcium carbonate filled systems and maintains stable foaming performance even at high filler loading.
5. 改善成品力学性能 / Enhance Mechanical Properties
提高板材抗弯强度、抗冲击性和尺寸稳定性，减少翘曲、变形、开裂。
It improves flexural strength, impact resistance and dimensional stability, and reduces warpage, deformation and cracking.
五、推荐添加量 / Recommended Dosage
