Le choix du meilleur additif pour votre projet peut être facilité par une connaissance approfondie des différents types d'additifs et de leurs utilisations.
Superplasticizers (SPs), also known as high variety water reducers, are additives used for building high strength concrete or to position self-compacting concrete. Plasticizers are chemical compounds enabling the creation of concrete with roughly 15% considerably less water content.
Generation process: polypropylene is made by chain-progress polymerization, while polystyrene is created by free of charge radical vinyl polymerization.

The expression tacticity describes for polypropylene how the methyl team is oriented during the polymer chain. Professional polypropylene is generally isotactic. This post thus normally refers to isotactic polypropylene, Except mentioned if not. The tacticity is usually indicated in p.c, utilizing the isotactic index (Based on DIN 16774). The index is measured by identifying the fraction of the polymer insoluble in boiling heptane.

"The bad insulation performance of double glass, generally resulting from flooding fog interlayer resulting from air vapor, even a moldy, so some companies are frequently used between two pieces of glass with aluminum in aluminum strip with holes, pores about the granular desiccant" processing "technique, the truth is only A short lived go over, didn't elevate any insulation overall performance of double glass desiccant, quite a long time once the failure, or betray.
Polypropylene Plastic: Broadly used in producing diverse plastic products, Polypropylene granules are utilized in production diverse products and solutions like packaging components, textiles, and plastics.
Paint that can help keep properties cooler on warm, sunny days. In every one of these strategies and much more, 3M Glass Bubbles are supporting a variety of industrial sectors resolve their layout worries and reach new levels of effectiveness and productivity.
Make contact with a sales rep To learn more, which include formulation guidance or questions on a particular application.
Charge: While polypropylene is commonly inexpensive to manufacture than polyester, this does not normally indicate the completed merchandise might be more affordable. The pricing is intensely motivated by aspects for example brand name names and item categories.
Two most critical technological properties of each of the supported catalysts are high productiveness and also admix concrete a high portion from the crystalline isotactic polymer they generate at 70–80 °C underneath conventional polymerization circumstances. Industrial synthesis of isotactic polypropylene is often completed both from the medium of liquid propylene or in fuel-period reactors.
Hollow glass window, is often on the surface of super spacer sealing adequate depth of sizzling melt butyl rubber, to make certain that the hollow glass sealing program with anti moisture permeability enough.
