SYSTEM HOUSE
A Systems House is a critical unit in the polyurethane industry. It oversees the formulation of new polyurethane systems on a laboratory scale. Successful systems are subsequently produced on a commercial scale in the blending plant for sale to customers.
The manufacturers of formulated systems (System House) develop, within their own laboratories, special formulations that allow to create foams with physical and chemical characteristics and performance suited to different uses.
Polyurethane Systems House is used in multiple industries - automotive, aerospace, industrial, construction. PU Systems are designed as recipes for foams (e.g., for furniture and insulation), for elastomers, e.g., for automotive.
VISCO-ELASTIC FOAM SYSTEM
FEATURES
Visco-elastic foam is also known as Memory foam and can be designated by customer needs with following details: Density • Hardness • Recovery Time • Cell Openness • Temperature Sensitivity • Surface Softness • Surface Stickness • Tear and Tensile Strength.
USING METHODS
Polyol and modified MDI system should be stored at 24 +/- 2°C.
Polyol system should be vigorously pre-mixed at least 10 min in a working tank for fine cell.
Pre-mixed polyol system should be mixed about 30 sec additionally in a foaming head.
MDI is added in this stage and should ne mixed about 10 sec with the pre-polyol system.
Lastly, it is poured on the foaming box.
APPLICATIONS
Mattresses, Topper, Sofas, Cushions
POPULAR SYSTEM
General foam
Density 60kg
Air permeable foam
Density 50kg
ISO System
Modified MDI system
ECONOMIC SYSTEM
Specialized for 50kg density
Using any kinds of most common polymeric MDI
P-MDI is lower price and easily purchased than specific MDI
SPECIFIC SYSTEM
It is 55kg foam at low sea level area
It is 50kg foam at 1.000m altitude
In spite of density difference its quality is almost the same and the feeling is very comfortable
PILLOW SYSTEM
FEATURES
All densities from 45 to 70kg.
Mixing ratio (polyol system versus MDI)
FOAMING CONDITIONS METHODS
Foaming conditions: mold temperature 500 C, demolding time 5-6 mins.
APPLICATIONS
Pillow, neck pillow, in-sole, indoor mat.
Pillow size: 45*30*8/10 cm


SPECIAL FOAM SYSTEM
FEATURES
Special foam system follow new trends and satisfy market specific applications.
In the future, more specific and unique products will be required.
According to new energy innovation, electric automotive and appliance is already coming.
EV battery encapsulated system is for the use to fix and protect cylinder battery.
High technology know-how is eesential to meet safety against fire, high temperature, and electric conductivity.
APPLICATIONS
In-door shoes, electric vehicles, mattresses
REMARKS
Polyol system should be mixed about 10 min to make homogenous state. Specific mixing ratio and using method should be followed.
Also, recommended MDI should be used to satisfy the specific needs.
SEMI-RIGID FOAM SYSTEM
FEATURES
High tensile strength and elongation
High compression strength
Very stable molding properties without brittle and wrinkle
No scorching appearance
Good air porosity
APPLICATIONS
Automobile headliner, automobile sunvisor
