Key Features of Household Refrigerator and Freezer Construction<\/strong>
Some of the most important and distinctive features in the construction of household refrigerators and freezers include optimal thermal insulation and energy consumption, high structural durability, elegant design, and lightweight portability.

Over the past decades, chemical and polymer studies have introduced the remarkable polyurethane materials to the home appliance industry to achieve these goals.

Rigid polyurethane foams, with their strong yet lightweight structure, provide high insulation efficiency. This has led to energy savings while ensuring elegance and aesthetic appeal in the design of household refrigerators and freezers.<\/p>

Achieving these features depends on the manufacturing process and formulation of the rigid polyurethane polyol, which, based on a set of structural characteristics, enables the attainment of these objectives.<\/p>

The technical features of Razin Polyurethane's rigid polyol for refrigerators are outlined below to achieve these goals.<\/p>


Technical Features of Household Refrigerator Grade Polyol<\/strong><\/p>

  • The refrigerator-grade polyol must be formulated to deliver the highest possible insulation coefficient.<\/li>
  • The gel time and demolding time in the production of household refrigerator-grade polyol should be very short and compatible with the customer's automated production lines.<\/li>
  • This grade must be formulated to have an optimal density that provides effective insulation while maximizing adhesion to the refrigerator body.<\/li>
  • The refrigerator-grade polyol should exhibit the highest mold fillability at the optimal insulation density.<\/li>
  • It should have the lowest shrinkage and draw (elongation) of the foam.<\/li>
  • The raw material consumption of polyol and isocyanate to achieve the optimal density should be minimized.<\/li><\/ul>


    Applications of Razin Household Refrigerator Grade Polyol<\/strong><\/p>

    • Hotel refrigerators and freezers<\/li>
    • Single-door to four-door refrigerators<\/li>
    • Combo refrigerators and freezers<\/li>
    • Twin refrigerators and freezers<\/li>
    • Side-by-side refrigerators<\/li>
    • ... (additional applications as appropriate)<\/li><\/ul>


      Razin Polyurethane\u2019s Refrigerator Grade Polyol Series<\/strong>
      In the household refrigerator sector, Razin Polyurethane produces three grades: 102, 101, and 100 Razapol, all gas-free. These grades are tailored based on customer needs and production volume of refrigerator manufacturers. All of these grades demonstrate high surface bonding and curing quality, with free density ranging from 23 to 25 kg\/m\u00b3, achieved with 10% cyclopentane gas.\u000bThe most distinguishing feature of these refrigerator grades is their demolding time, allowing Razin polyurethane products to cater to various production lines through a diverse range of grades.<\/p>
