Chemical name: 2, 5 - two (5 - tert-butyl - 2 - benzo pbo) thiophene

Applicable to chemical fiber without fluorescent whitening agent. Especially in the recycled material, reworked material imitation dahua chemiacl chemical fiber have a significant effect, high value-added products. Suggested usage: sinochem imitation dahua chemiacl 400-800 - g/T; Sinochem this white 800 g - 1.5 g/T; The concrete experiment to determine, please. The product is different from the fluorescent whitening agent and titanium whitening principle of fluorescent whitening agent is by absorbing invisible ultraviolet uv light into visible light and show white; Titanium dioxide is through the size of dispersing cover; But whether with fluorescent whitening agent or titanium dioxide whitening, the impression of chemical fiber with dark background, is good regeneration recycling materials also change not bottom! The company produced without fluorescent whitening agent is very good solve the problem, this product is make full use of the high temperature of resin process into its molecular, molecular bonds of damaged during its processing reduction treatment so as to achieve the effect of white significantly. This product can be used with titanium dioxide, this product can be used with fluorescent whitening agent, white chemical fiber production. Due to the need of the technical secret, the company is unfavorable to open composition and molecular structure, strong whitening effect, chemical fibber luster whiten, no fluorescence, brightness is good, can significantly improve the added value of chemical fiber products. Improve the quality of finished goods and class, good regeneration recycling flow of chemical fiber luster and new material approximation, is natural, the base of color is not dark. This product does not affect on the post processing of textiles Packing and storage: 1, 25 kilogram cardboard barrels. 2, this product is non-combustible, smell excitant, sensitive to people with allergies or asthma. Finished as soon as possible after 3, unsealed, prolonged exposure to the air oxidation failure. 4, sealing the shade.

Product introduction: KSN is a high concentration of added way, application in plastic and polyester fiber optical brightener. * high brightness of optical brightener * whitening effect is normal to blue light products and make the color more bright purple * a significant resistance transference in LDPE Features: Outside the yellow powder Chemical properties Benzo thiazole derivatives Ion features Non-ionic substances The melting point of 250-300 ℃ Storage stability In the case of moisture and sunlight is not stable But dilution degrees Does not dissolve in water Solubility (25 ℃) Propyl ketone 80 mg/l Dimethyl amide 800 mg/l Perc 250 mg/l Methyl benzene 500 mg/l Methanol (9:1) 970 mg/l Thermal stability is suitable for plastic and synthetic polymer processing To use: KSN is very suitable for processing of synthetic high polymer in the process of whitening, such as used in the film, injection molding, compression molding, chemical fiber, bristles and colored wax dyeing of wool. The using methods similar to pigment, plastic additives or chemical additives. Method of use: In color plastic additives for 20-300 parts per million. Transparent plastic is usually lower than the end of 5-20 PPM is enough. Thermoplastic PVC maximum dosage is 100 PPM, hard PVC is 500 PPM. Polyester fiber average usage for 100-250 PPM. The product can or polycondensation reaction during the ester exchange reaction and mixed compound with time to add, it also can be in the form of brighten up the processing of the masterbatch added to plastics and fiber, so to lighten up the amount of the masterbatch in 0.5 to 20%.

Fluorescent Brightener KCB Alias: KCB; Fluorescent Brightener 367; FLUORESCENT BRIGHTENER KCB; 1, 4 - bis (benziazolyl - 2 - yl -) naphth - alene; FBA 367; 1, 4 - Bis (2 - benzoxazoly) naphthalene; Optical Brightener KCB; C.I. 367; ; 2, 2 '- naphthalene - 1, 4 - diylbis (1, 3 - benzoxazole) CAS no. : 5089-22-5; The 63310-10-1 Molecular formula: C24H14N2O2 Molecular weight: 362.3802 Appearance: yellowish green crystalline powder Melting point: 210-212 ℃ Fluorescence tone: LanLiang densities The main purpose Mainly used for whitening, synthetic fibre and plastic products for EVA foam products, EVA material particles, plastic foam products have the effect of special significant, there has been a marked increase of colored plastic products gorgeous effect, also used for PE, PP, PVC, PS, ABS, etc Usage and dosage: dissolve evenly dispersed in the product, 0.01% - 0.05% (per 100 kg product usage 10-50 g). 25 kg bag pack: 25 kg cardboard barrels, carton double lined with plastic bags or packing according to the requirements of customers.

Plastic special fluorescent whitening agent FP - 127 Technical indicators: Shallow green opal or yellow opal powder appearance Light blue and white (similar to standard sample) A purity of 98% or more Melting point of 230-280 ℃ Fineness by 100 sieve (5%) or less Performance and features: This product is light green or milk green powder, non-toxic, tasteless, soluble in paraffin, fat, mineral oils, paraffin and most organic solvents, spectral absorption maximum value is 375 mm (in ethanol) Application scope: 127 is widely used in PVC, PE, PP, ABS, PS and unsaturated resin, thermoplastic plastic and paint, ink and oil soluble coatings such as whitening.
