▪ Trans-1,4-polyisoprene (TPI)- Known as synthetic balata rubber, shares the same structure and properties as natural gutta-percha and balata. The monomer used to synthesize this polymer is isoprene. TPI has the exact same chemical composition (C₅H₈)ₙ as cis-1,4-polyisoprene (CPI) or natural rubber (NR). However, due to their opposite molecular chain configurations—NR being cis-1,4 structured and remaining a soft elastomer at room temperature, while TPI is trans-1,4 structured—TPI crystallizes rapidly below 60°C, forming folded chains. This results in a crystalline polymer with high hardness and tensile strength. ▪ Specificaiton: TPI-40,60,80 ▪ Form: Granule, Powder.

Sodium Naphthalene Sulfonate Formaldehyde (SNF) is an anionic surfactant and belongs to the naphthalene-based superplasticizer. It has good dispersibility, high water reduction rate and strengthening effect. It is one of the most widely used traditional water reducers in the field of concrete admixtures. 2. Main performance characteristics ✅ High water reduction rate (15%-25%), significantly reducing the amount of water used in concrete mixing and improving strength. ✅ Improve fluidity, enhance the pumpability and workability of concrete. ✅ Enhance the early and late strength of concrete, and improve the compressive and flexural strength. ✅ Does not contain chloride ions, will not corrode steel bars, and improve the durability of concrete. ✅ Wide adaptability, suitable for various cements and mineral admixtures. ✅ High cost performance, lower cost than polycarboxylate water reducer, widely used in conventional concrete projects. 3. Main application areas SNF is a classic naphthalene-based water reducer, suitable for various concrete and cement-based materials, such as: (1) General Concrete Applicable to C15-C60 grade general concrete to improve construction performance. (2) Pumped Concrete Enhance the pumpability of concrete, reduce pipeline blockage, and improve construction efficiency. (3) Precast Concrete Improve early strength, shorten demoulding time, and improve precast production efficiency. (4) Mass Concrete Control water-cement ratio, reduce shrinkage cracks, and improve durability. Typical applications: dams, underground projects, and infrastructure construction. (5) Mortar & Cement Products Used for self-leveling mortar, dry mortar, grouting materials, brick and tile products, to improve fluidity. (6) Ceramics & Refractories As a dispersant, it improves the rheological properties of ceramic green bodies and refractories and improves the molding quality. 4. Usage Recommended dosage: 0.5%-1.5% (by cement mass ratio). It can be directly added to concrete or used in combination with retarders, air entraining agents, etc. It is recommended to conduct a compatibility test before use to optimize the mix ratio. 6. Conclusion Sodium naphthalenesulfonate formaldehyde condensate (SNF) is a cost-effective and widely used classic naphthalene-based high-efficiency water reducer. It is widely used in ordinary concrete, pumped concrete, prefabricated components, mortar and ceramics. Although its slump retention is not as good as that of polycarboxylate water reducer (PCE), it is still one of the preferred admixtures for many engineering projects due to its good water reduction effect and low cost advantages.

Introduction to Polycarboxylate Superplasticizer (PCE) 1. What is Polycarboxylate Superplasticizer? Polycarboxylate Superplasticizer (PCE) is a new generation of high-performance concrete admixture with high water reduction rate, good slump retention, environmental protection and high adaptability. Compared with traditional naphthalene and melamine water reducers, polycarboxylate superplasticizer has better performance and has become the preferred admixture for **modern high-performance concrete (HPC)**. 2. Main performance characteristics of polycarboxylate superplasticizer ✅ High water reduction rate (25%-40%): significantly reduce the water consumption of concrete and improve strength. ✅ Good fluidity: greatly improve the fluidity of concrete, suitable for self-compacting concrete and pumping construction. ✅ Excellent slump retention: maintain the workability of concrete for a long time, suitable for long-distance transportation. ✅ Environmental protection: does not contain formaldehyde, is environmentally friendly, and meets the requirements of green buildings. ✅ Strong adaptability: suitable for different types of cement, mineral admixtures and different construction conditions. ✅ Low shrinkage: Reduce shrinkage and cracks of concrete and improve durability. 3. Main application areas Polycarboxylic acid high-efficiency water reducer is suitable for various concrete projects, especially those that require high fluidity, high strength and high durability, such as: (1) High-strength concrete Applicable to high-strength concrete of C50-C100 and above, improve early strength and shorten construction period. Typical applications: high-rise buildings, bridges, and large-span structures. (2) Pumped concrete Enhance the pumpability of concrete and improve construction efficiency. Applicable to high-rise buildings, large-volume concrete, and long-distance pumping. (3) Self-leveling and self-compacting concrete Applicable to floor projects and underground projects, reduce vibration and improve construction quality. (4) Mass Concrete Low water-cement ratio, reduced hydration heat, and prevent cracking of mass concrete. Typical applications: dams, tunnels, nuclear power plants, ports. (5) Precast Concrete Improve early strength, accelerate demoulding, and improve production efficiency. Applicable to factory production of precast beams, pipe piles, PC components, etc. (6) Durable Concrete Improve impermeability, frost resistance, and sulfate corrosion resistance, and extend the service life of concrete. Applicable to marine concrete, underground structures, and transportation infrastructure. 4. Usage method Recommended dosage: 0.1%-0.3% (by cement mass ratio). It can be used alone or compounded with retarders, air entraining agents, etc. to improve comprehensive performance. It is recommended to conduct a compatibility test before use to optimize the mix ratio. Polycarboxylate high-efficiency water-reducing agent (PCE) is currently the most advanced concrete admixture, widely used in high-strength, pumpable, self-leveling and precast concrete. It has high water reduction rate, excellent slump retention, environmental protection and high adaptability.
