Application of BENZOFLEX 9-88

1. Plasticizer for polyvinyl chloride, polyvinyl acetate and polyurethane. Strong solvent, good compatibility, low volatility, excellent durability, oil resistance and pollution resistance.

2, commonly used in high-filled PVC floor materials and extruded plastics, can improve processability, reduce processing temperature and shorten processing cycle. When used for unfilled films and sheets, the transparency and surface gloss of the article are good.

3. It can be used as a plasticizer for castable polyurethane. Production of printing rubber rolls and other products to improve the elasticity of the products.

Used in cosmetics, it can be used as a high-grade solubilizer: a lipophilic cosmetic raw material, especially an antiperspirant, a moisture-proofing agent and a water-insoluble powdery product auxiliary suspending agent, which can be used as a high-quality advanced solubilizer.


BENZOFLEX 9-88 SG is a highly compatible plasticizer for use in two-component polyurethane systems. It is a highly effective non-phthalate plasticizer.

Widely used in: decal / graphics / printing industry; polyurethane (polyurethane casting); polyurethane adhesive; polyurethane sealant.


Benzoflex 9-88 SG is suitable for cast polyurethane products, giving the system minimal cure interference and excellent compatibility. In addition, Benzoflex 9-88 SG also increases the filler loading of polyurethane systems, increases tear strength and resilience, and reduces the expansion deformation of materials in specific solvents. In production, it is applicable to both machine and manual feed mixing methods.


Benzoflex 9-88 is a highly soluble general purpose plasticizer that has been used for many years. Its many uses include elastic flooring, adhesive artificial leathercloth and caulking cream. Although benzoflex 9-88 is still a good plasticizer, recent developments such as benzoflex 2088 and benzoflex 2160 allow compounds to be formulated with high solubility. Plasticizers have low VOC content while controlling rheology.


Benzoflex 9-88 is a highly soluble monomer plasticizer. This is a special solvator for PVC, energy irrigating performance improves processing steps to lower gel and fusion temperatures. This unusual affinity for PVC is also reflected in the test's fate Containing vinyl benzoflex 9-88 shows good resistance. benzoflex 9-88 is in the transportation field to improve stain resistance, durability, and to give supplements.


Benzoflex 9-88 is also a latex adhesive to improve elasticity, tack and adhesion properties. Polyvinyl alcohol formaldehyde adhesive emulsion, which has been shown to improve film surface wetting. benzoflex 9-88 lowers the temperature required for heat sealing where it is dry The solids-polyvinyl alcohol adhesive is then fused to form a bond, such as an aluminum foil-aluminum foil composite. Other uses of benzofles 9-88 are a plasticizer for elastics such as urea nitrogen and SBR latex caulks and seals based on photovoltaics, Evergreen and acrylic; polyvinyl concentrates are being developed for colored concentrates. Benzofles 9-88 has also been identified as an advantageous fracture for polyurethane casting.
