Products & Informations

SBR FOOD -CH 1028 is a food grade SSBR. Which is produced by hexane solution, the solution copolymerization of butadiene and styrene.

Using butyllithium as catalyst, the solvents and volatiles are removed by hot water, dewaterer and expander.

It is an equivalent of SBR FOOD-CH 1028. Which used in bubble/chewing gum base and food contact.

APPLICATIONS & USES

Bubble gum base

Chewing gum base

Comparison of the quality of China dissolved polystyrene-

butadiene rubber(SSBR FOOD CH) with USA and

MEXICO Emulsion polystyrene-butadiene rubber

( ESBR FOOD)

1

The United States, Mexico produced emulsion polystyrene-butadiene rubber English name ESBR,

ESBR is representative of the use of rosin saponification liquid for polymerization reaction

production of styrene-butadiene rubber products, and monomer in the reaction process

(butadiene, styrene) polymerization reaction rate is only about 60%-70%, after the end

of the reaction and then through the recovery device, the remaining 35% of the styrene

monomer that has not been completely reacted is recovered, and the polymerized glue

is separated from the emulsion polystyrene-butadiene rubber product after steam

agglomeration.

Part of the rosin acid is converted into organic acids and saponifieds, so the finished

emulsion polystyrene-butadiene rubber contains 5%-6% organic acids and a small amount

of saponification and other residues, so the purity of emulsion polystyrene-butadiene

rubber is only about 95%, while Mexico's emulsion polystyrene-butadiene rubber

purity is only about 92%.

There are a number of enterprises specializing in the production of emulsion polystyrene-

butadiene rubber, the production of styrene-butadiene rubber products and imported food

-grade emulsion polystyrene-butadiene rubber products performance is basically the

same, the domestic factory production of emulsion polystyrene-butadiene rubber

name specification model ESBR a 1502 type, but is no enterprise to consider the

use as a food additive, even if you want to use it in the food additive industry,

the national regulatory authorities clearly stated that according to the national

standard inspection of food-grade styrene-butadiene rubber, it is impossible to

pass the audit, Therefore, although the indicators of domestic production of dairy

polystyrene-butadiene rubber are exactly the same as imported dairy polystyrene-

butadiene rubber, but that is, domestic dairy polystyrene-butadiene rubber can not

be used as a food additive product, domestic production enterprises are clear, dairy

polystyrene-butadiene rubber process production products can not meet the food

additive styrene-butadiene rubber national standard indicators!

Now the domestic Ningbo Bowhong high-tech enterprises introduced advanced dissolved

polystyrene-butadiene rubber projects, after process adjustment, successfully produced

food-grade dissolved styrene-butadiene rubber products SSBR, tested by national

authorities according to international and domestic food-grade styrene-butadiene

rubber standards, the product indicators fully comply with the national standards

for food additives butadiene butadiene rubber, the English name of dissolved polystyrene-

butadiene rubber products SSBR, where $ indicates the use of solvent oil (hexane)

polymerization reaction of styrene-butadiene rubber products, its process requirements

are high, product purity is high, Its process requires that the butadiene raw material

is first purified and refined to 99.99% purity of butadiene, styrene is dried to achieve

99.9% purity, solvent oil water quality must be below 10ppm, the use of butyl lithium

catalyst, rapid reaction, monomer reaction rate of 99.99%, and then through the

agglomeration process, post-processing process, molding packaging, finished

products out of the warehouse!

It can be seen that emulsion polystyrene-butadiene gum and dissolved polystyrene-

butadiene gum are three completely different processes, and the quality, quality and

physical and chemical indicators of the products are completely different.

According to the domestic food rubber national standard and the international food

rubber standard comparison "American FCC8, Spanish Royal Decree, French Glue
