Product Description Silicone oil 3618 3618 is used to produce polyether polyurethane flexible foam silicone surfactant general. Chemically it is a high activity non-hydrolyzable polysilane - polyoxyalkylene copolymer stabilizer.
Physical Properties |
Viscosity (25 ℃) | 500-1000 mPas |
Density (25 ℃) | 1.01-1.04g/cm3 |
PH value (4% water soluble) | 5.5-8.0 |
Cloud point (4% water soluble) | 37-42℃ |
Recommended storage conditions 3618 storage stability of at least 12 months, provided the case is to be intact and to prevent scorching and giant placed in a cold environment. 3618 is lower than the freezing point of -10 ℃, it is able hardy. But we still hope to rise to room temperature before using. Production guidance 3618 may be used alone or mixed in water and amine input mixing head. In general the soft foam formulations which can dissolve in various proportions Mixture, 3618 proved a tertiary amine at room temperature and under a common stability up to at least five days. Application 3618 as polyether soft foam stabilizer, because of his high activity can be obtained in the production of higher economic efficiency. When the foam stability of the support system requires more time, particularly in low-density or for containing a hydroxyl value of 56 of the pure PPG polyether system, it is better reflect its advantages. Although 3618 is high activity, it is a very wide range of processing. So it is absolutely suitable for low-density and high-density formula. 3618 The use of a blowing agent is not limited types and different formulations. Its efficiency and reliability is reflected in: it can be used for the common variety of blowing agents currently on the market and can perform continuous foaming machine box or other safe production. His high activity brought about by high German gas production volume and thinner bottom skin, give foam manufacturers to bring high economic efficiency. Because of its high activity, even in the use of silicone oil than other conventional with 10% less in the case, but also a slightly lower foam density (e.g., by the 31.8kg/m3 to 31.6kg/m3 to 17.7 become 17.05kg / m3). . If the formula contains flame retardants, 3618 can enhance the flame retardant effect. It's such a special effect makes 3618 in the production of flame-retardant foam to achieve or produce flame retardant standard composites popular manufacturers welcome. 3618 for the convenience of our customers will be economical and popular for the production or improve your own recipe, is to provide the following reference formulations. 3618 guidance for the production of flexible foam formulations

Above is only as a reference data. In actual production, according to the particular machine and chemical conditions (polyether amine type of activity) Please be adjusted accordingly. The formula is obtained at 22 ℃ under, for hotter or cooler environment, coping catalyst adjust accordingly. Packing: 210kg per iron drum
