Polyurethane Foams
It is used for making soft foams for furniture and mattresses for comfort. Also, it is used in hard foams in building insulation to save energy and minimize heating costs.
What is Castor-Based Biopolyol?
Castor-based biopolyol is a natural material made from castor oil, which is extracted from non-edible castor beans grown on lands that don’t compete with food crops. This bio-based polyol offers a green replacement for regular polyols, which are traditionally made from crude oil.
Castor biopolyol performs like traditional polyols but is safe for the planet, as it comes from renewable plant sources.
Applications & Uses of Castor-Based Bio Polyol:
Adhesives and Glues
Castor-Based Bio Polyol helps in creating strong bonds between molecules of materials. It has strong resistance to chemicals, weather, and temperature, thus, suitable for making long-lasting products.
Coatings and Paints
This material, when used in paints, offers complete protection against corrosion, UV rays, and other environmental damage.
Sealants
They help to create flexible seals that prevent air and water leaks in buildings. This enhances energy efficiency in the buildings.
Construction Materials
Incorporated into insulation panels, roofing, and building parts to improve thermal performance and save energy.
Furniture Manufacturing
Provide foam layers for chairs, sofas, and mattresses that make seating and bedding more comfortable. Also offers shape retention that lasts for years.
Packaging Industry
Protective foam keeps products safe during shipping and storage. Thanks to bio-based polyol Castrol for minimizing damage as well as waste.
Automotive Industry
Castor biopolyol is used in the automotive sector. Dashboards, seats, and bumpers stay safe, comfy, and strong in daily use. They can easily handle regular use and temperature variations.
Castor-Based Bio Polyol Formula & Composition
The castor-based bio polyol formula is mainly made from ricinoleic acid (C₁₈H₃₄O₃), which makes up about 85-90% of castor oil. This acid has a special structure with a hydroxyl group that makes it perfect for making polyurethane.
Castor oil is changed into polyols by simple chemical steps. These polyols have hydroxyl numbers between 150-400 mg KOH/g. They are mostly made of ricinoleic acid (85-90%), with small amounts of oleic acid (3-5%), linoleic acid (2-4%), and other fatty acids (2-5%). This makes a steady polyol that works well in making many products.
Benefits of Using Bio-Based Polyols
They help reduce pollution by cutting carbon emissions. Bio-based polyols produce up to 70% less CO₂ compared to petroleum-based ones.
These polyols are easier for nature to handle. They show 60–80% biodegradation within 28 days in standard tests.
They are safer during fire risks. The natural phosphorus in them improves flame resistance and safety.
They help to make polyurethane materials sturdy and more flexible. The final products made by using bio-based polyol have better strength and longer life.
They are more cost-friendly. Since they don’t depend much on costly petroleum or crude oil, their prices stay stable. This helps companies to plan their cost better.
Technical Specifications & Grades
Our bio-based polyols come in different grades to meet various needs. We offer hydroxyl numbers from 150-400 mg KOH/g, acid values below 2 mg KOH/g, and thickness from 800-5000 cP at 25°C.
You can choose molecular weights from 400-2000 g/mol with functionality from 2.0-4.5. Other important specs include water content below 0.1%, color values less than 50 APHA, and flash points above 200°C for safe handling.
FAQs:
Bio-based polyols come from plants like castor oil, while
petroleum ones come from fossil fuels. Bio-based types are eco-friendly, cut
carbon emissions, and often perform better.
Yes, in most foams, coatings, and adhesives. Some uses may
need small recipe changes. It can replace 20–100% depending on the product.
12–18 months if stored below 40°C in sealed containers,
away from moisture and sunlight.
They give strength, flexibility, and resistance in
polyurethane. Bio-based types add eco-friendliness, fire resistance, stable
costs, and renewable sourcing.
