Product description
Parameters

HYPOL material from Dow Chemical is polyurethane prepolymer – isocyanate terminated reactive liquid, which has a strong hydrophilicity.

The prepolymer is mixed with water, and products with different performances, such as foam, gel and glue, can be prepared only by controlling the amount of added water without adding a catalyst or additional heating.

Characteristics of HYPOL materials

1

Strong designability

HYPOL prepolymers can be made into foam, gel and glue according to different water absorption specific gravity.

For example, by adding one HYLOP to 5-20 shares of water, you can get gel, and by adding one HYLOP to 0.5-3 shares of water, you can get foam.

Hydrophily

HYPOL prepolymer can absorb water 20 times its own weight and can keep water from losing.

Application 1: Non-latex powder puff

Popularization of science: Powder puffs fall into two types: latex and non-latex

Latex powder puff: It’s mainly made of rubber materials (NR natural latex, NBR nitrile latex, SBR styrene-butadiene latex). Its long-term use will cause slight harm to human body, such as skin allergy. It smells like rubber. When using with oily cosmetics, it will be flaky and have no oil resistance.

Non-latex powder puff: It is made of hydrophilic polyurethane and international advanced polymer technology. It does not contain latex. Compared with general synthetic latex sponge, it has strong stretching, tearing and abrasion resistance, does not turn yellow due to sweat erosion, and has its own bacteriostatic component, which can inhibit bacteria growth, thus it will not generate peculiar smell, and will greatly reduce the allergic probability. Its surface is soft and conformable, and it can absorb oil and degrease, and is not flaky. It has been gradually received in the powder puff industry and is favored by the majority of users.

Application 2: Medical foam dressing

Foam dressing is a sterile disposable, soft, absorbent and adhesive polyurethane foam dressing, which can provide an ideal moist wound healing environment and effectively absorb exudate.

It is suitable for wounds with many exudates, such as lower limb ulceration and pressure sores, can be used for second-degree burns, postoperative wounds and skin abrasions, and can be used to provide protection for suitable wounds in the whole healing process.

Application 3: Gardening

The roof is covered with a layer of specially-made black foam, which is heat-insulated and absorbs water. So what the absorbed water will be used?

Rooftop gardening, planting more in the soil, the retained water and nutrients can fully nourish the plants and build a beautiful hanging garden.

→Slow release

HYPOL can easily wrap functional additives such as acrylic resin, surfactant, wetting agent, foaming agent, essence and spice, pigment, bactericide, filler (including organic filler), fiber, fungicide and preservative.
