Methyl propionate is an organic compound with the chemical formula C4H8O2. It is a colorless and transparent liquid, slightly soluble in water and miscible in ethanol and ether. It is often used as a solvent for nitrocellulose, nitrocellulose paint, paint, varnish, etc. it can also be used as a solvent for spices and condiments, and as an intermediate in organic synthesis. It can be used as a solvent for nitrocellulose, nitrocellulose paint, paint, varnish, etc. It can also be used as a solvent for spices and condiments, as well as an intermediate in organic synthesis.

Polyformaldehyde Resins, also known as Polyoxymethylene Resins (POM), are thermoplastic resins with excellent comprehensive properties. POM resin has a high elastic modulus, hardness, rigidity and mechanical properties in a large temperature range, can be used for a long time below 104 ?, embrittlement temperature -40 ?, and very little water absorption. At the same time, its outstanding feature is the low friction coefficient, the dynamic friction coefficient is the same as the static friction coefficient, and the self-lubricating wear resistance is excellent. The mechanical properties of POM resin are similar to metals, and the specific gravity is small, so it is widely used to replace metal materials such as steel, copper, zinc, aluminum and other plastics. It is also called “the metal in plastic”.

Epoxy resin refers to an organic polymer compound containing two or more epoxy groups in its molecule. Its molecular structure is characterized by the presence of active epoxy groups in the molecular chain. The epoxy groups can be located at the end, in the middle of the molecular chain, or in a cyclic structure.

SL TEC has over 15 year experience in technology R&D, plant design, engineering, and operation in acetic acid production industry. We have several referred plants and we can ensure the safe, long-term and stable running of the plant.

With over 10 years experience, SL TEC focus on formaldehyde production technology based on silver contact process(or silver catalyzed process). A lower methanol consumption, higher formalin product concentration, high export steam capacity and ease of operation are our features, which makes it the best technical and economically viable solution. Every unit operation including methanol evaporation, catalytic reaction, absorption, off-gas treatment has optional design to at best satisfy the customer`s needs.

We offer complete package solutions for chemical distillation plant/distillation design/distillation tailoring using all-component analysis, process simulation, and a process automation package. Moreover, we also provide corresponding chemical sewage treatment solutions to satisfy the customers. 

 Who was honored as the technical center of national chemical packing tower and internal fitting in 1990, and whose “ High Efficiency Packing Column with New Type Column Internals” have been listed as the key marketing project among China’s “the Eighth Five-Year Plan” and “the Ninth Five-Year Plan” technology achievements.

Each periodic ripple of the Zupak is composed of more than four intermittent planar graphic sheets located on four planes. The lateral projection shape is two interlaced corrugated lines. The uniform parallelogram channel on the filler has completely replaced the circular holes on the regular structured packing. It can not only save 8.5% of the material, but also increase the specific surface area of the corresponding quantity. The packing has the advantages of low pressure, large flux, good transversal air permeability and high separation ability. It can be widely used in the industrial fields of distillation, absorption, extraction, heat exchange, washing and so on.

ACR is a copolymer of monomers such as methyl methacrylate and acrylate. ACR is the best impact modifier developed in recent years. It can increase the impact strength of materials dozens of times. ACR is an impact modifier with a core-shell structure. The shell is composed of methyl methacrylate-ethyl acrylate polymer, and the segments with rubber elastomer cross-linked by butyl acrylate as the core are distributed in the inner layer of the particles. It is especially suitable for impact modification of PVC plastic products for outdoor use. The use of ACR as an impact modifier in PVC plastic door and window profiles has good processing performance, smooth surface, good aging resistance, and high welding fillet strength compared with other modifiers. Features, but the price is about 1/3 higher than CPE. Commonly used brands abroad such as K-355, generally use 6-10 parts.

Titanium dioxide, also known as titanium oxide or titania, is the naturally occuring oxide of titanium,chemical formula TiO2. When used as a pigment, it is called titanium white,Pigment white. Generally it is sourced from ilmenite, tutile and anatase. It has a wide range of applications, from paint to sunscreen to food coloring. R838 is produced by sulfate process, It is a Rutile TiO2 pigment which is Inorganic Si, Al surface coating, organic surface treating. Has optical properties of partial blue phase, good whiteness,good optical properties and hiding power, good durability and dispersion etc. Product appearance: white powder.
