LT2202 Polyether Polyol

Thermal Insulation Spraying Applications

Cold storage rooms, grain silos, fruit and vegetable warehouses, chemical storage tanks, refrigerated trucks, and containers (roofs, floors and walls)
Residential and commercial insulation projects such as Villas, wine cellars, buildings, and KTV soundproof rooms
Cold storage machine rooms, refrigeration pipelines, storage tanks, and low-temperature pools
Underground thermal energy storage pools and chilled/hot water tanks
Roof insulation in livestock facilities such as chicken and duck houses and etc

LT2202 is a premium two-component polyurethane system formulated with polyether polyol, polyester polyol, foam stabilizer, catalyst, blowing agent, and flame retardant. Combined with polymeric MDI, it delivers superior insulation performance, excellent processability, and long-term durability.

Isocyanate Component
Isocyanate: Polymeric MDI

Applications & Key Features

LT2202 is specially formulated for spray application on poultry and duck house ceilings.

Compliant with the latest European and American environmental standards, it offers lightweight properties, cost effective, short construction cycles, and is fully eco-friendly.

Designed for efficient and reliable application, LT2202 ensures durable coverage, ease of use, and environmentally safe performance.

Control Tests

The main testing parameters include reaction characteristics such as cream time and fiber time, and the core density of the free-rise foam.

Test Method: 120 g of total material at 25°C is poured into a 500 ml plastic cup to observe reaction behavior.

Parameter	Value
Agitator Speed (rpm)	1000–2000
Agitator Diameter (mm)	50
Mixing Time (s)	2–6
Notes: After mixing, pour the mixed ingredients into a new cup.
