As a leading China RDP manufacturer, Hebei InnoNew Material Technology Co., Ltd. provides high-quality and cost-effective Redispersible Polymer Powder that enhances adhesion, flexibility, and water resistance in cement-based products. Redispersible Polymer Powder (RDP), also known as VAE Powder or VAE Redispersible Polymer Powder, is one of the most essential additives in modern construction materials.
InnoNew Material’s VAE Redispersible Polymer Powder is a free-flowing white powder produced by spray-drying a Vinyl Acetate-Ethylene copolymer emulsion (VAE). When mixed with water, it redisperses into a stable polymer emulsion, maintaining the same properties as the original latex.
- Chemical Name: Vinyl Acetate-Ethylene Copolymer
- CAS No.: 24937-78-8
- HS Code: 3905290000
- Appearance: White free-flowing powder
- Solid Content: ≥ 98%
- Minimum Film-Forming Temperature (MFFT): 0–5°C
Main Functions and Advantages
- Improved Adhesion:
RDP improves bonding strength between mortar and substrates such as concrete, gypsum, or brick, ensuring excellent durability. - Enhanced Flexibility and Deformation Resistance:
It increases flexibility and reduces cracking in mortars and tile adhesives, especially under thermal or mechanical stress. - Better Water Retention and Workability:
VAE powder improves water retention, open time, and flowability, making cementitious mixtures easier to apply. - Freeze-Thaw and Impact Resistance:
The polymer film formed after curing provides resistance to weathering, water, and mechanical impact. - Environmental Safety:
Our RDP powder is non-toxic, low in VOCs, and environmentally friendly, aligning with global green building standards.
