What are the key differences between RDP powder and resin powder in construction?

Redispersible Polymer Powder:
– RDP powder is water-soluble additive. It is made from ethylene and vinyl acetate copolymers with polyvinyl alcohol as a protective colloid.
– It forms a flexible and water-resistant film when mixed with water. Offering strong bonding, alkali resistance, and improved mortar properties.
– The film it creates is flexible, water-resistant, and meets national standards.
– RDP powder excels in high bonding strength, waterproofing, and enhancing mortar properties. For example, adhesion, strength, plasticity, wear resistance, and workability.


Resin Powder:
– Resin powder is a modifier containing rubber, resin, polymer particles, and finely ground powder.
– It has average durability and wear resistance. But, its dispersion isn’t ideal, sometimes appearing granular with a pungent odor.
– Some resin powders may corrode surfaces, and their waterproofing is not strong.
– Weather and water resistance are lower than RDP powder, and they may degrade quickly under sunlight or in cavity construction.
– Resin powder lacks flexibility and isn’t suitable for most construction materials. Meeting standards mainly for bonding polystyrene boards.

What types of construction polymers are commonly used?

There are several types of construction polymers. Each comes with its unique properties and applications.


Cellulose Ethers
These include products like HPMC, HEMC/MHEC, and HEC. They are used as thickening agents and water-retaining agents in construction materials.


Polypropylene Fibers
PP synthetic fibers are added to concrete to improve tensile strength. It also reduces cracking and enhances durability.


Polyethylene Terephthalate (PET) Fibers
PET fibers are used for their thermal stability and resistance to chemicals. They reinforce concrete and improve crack resistance.

What are the advantages of polymer fibers in construction?

We often use polymer fibers as they’re durable and, of course, out of the cost-effective reason as well.


Synthetic polymer fibers are easy to use. You only need to add it during concrete mixing. They give your concrete a big boost in strength and endurance. Because of their long-lasting result, you don’t have to change or replace it.
