Product Description

  

Casting Polyurethane Prepolymer for PU Elastomer For Sports equipment dumbbells 
 

Medium viscosity, medium and low temperature curing polyether products. The advantages of the product are easy to use, long service life, fast demoulding and high strength. 
Mainly used for the production of polyurethane elastomer products with general requirements for medium and low temperature curing, such as fitness equipment encapsulation. 
 

(1) Weigh quantitative components A and B into two containers, vacuum until there are no largebubblesonthe surface, and reserve;(2) The temperature of A and B shall be controlled at about 40~50 ºC, and the mixing ratioshall beA:B=100:100. Evenly stir and vacuum. After mixing, it can be used for about 3~4 minutes;(3) Inject the mixed materials into the preheated mold coated with polyurethane special releaseagent,andthe mold temperature shall be controlled at 70~90 ºC. Pay attention to avoid too manybubbleswhenpouring. After the bubbles float up, burn them with flames. The controlled gel point that needs tobemoldedwith a vulcanizer is pressurized before the surface is not sticky but not completely hardened;(4) The product demoulding time is 15~30 minutes. Generally speaking, the larger the product is, thelongerthe demoulding time is. Please extend the demoulding time appropriately. If it is cured at roomtemperature,it has preliminary strength within 2 hours and demoulding strength within 3~4 hours;(5) After demoulding, the products shall be further post vulcanized at a temperature of 90~100ºCfor4~8hours. They can be used after being placed at room temperature for another week. The initial strengthcanbereached after curing at room temperature for 18 to 24 hours. If the performance fully meets the requirements,please leave it for more than 3 days.
