Natural rubber, in its milky sap, is tapped from the Hevea Brasiliensis tree. Most of the latex is either processed into sheets or solid crumb rubber. It can also be kept in its liquid form through use of chemicals to prevent the latex from coagulation.
In the solid form, the rubber sheets or crumbs are used in the manufacture of solid rubber based products, e.g. tyres etc., while the liquid form is used for dipping products such as gloves, balloons and condoms.
Technically Specified Rubber (TSR)
Rubber grading under TSR was established in the early 1970s. The rubber is graded by its dirt, ash, nitrogen content, volatile matter content and plasticity retention index. They have good processing characteristics and physical properties. Usually, such grades of rubber are high in green strength, tack, easy to mix and has low viscosity.
Common sources of TSR include Thailand, Indonesia, Malaysia, Vietnam, India etc. However quite recently the African and South American rubbers are gaining popularity. Most Asian countries have a nomenclature of labelling their standard rubbers with the country of their origin viz. Standard Malaysia Rubber as SMR, Standard Indonesia Rubber as SIR, Standard Thailand Rubber as STR and Standard Vietnam Rubber as SVR. These are used in high performance passenger tyres, motorcycle and bicycle tyres, heavy load truck tyres, conveyor belt, inner tubes and hose.
Ribbed smoked sheets are smoked rubber sheets that have been processed from USS (unsmoked sheets).
They are general classified into 5 classes according to purity, elasticity and color.
RSS1 denotes the highest quality and those that are of an inferior quality are classified, in descending order, into RSS2, RSS3, RSS4 and RSS5.
Ribbed smoked sheets serve as the raw material in the production of many products, including car tires, conveyor belts, rubber pipes, shoes, and automotive parts.
We can supply RSS Thailand Origin, Indonesia Origin
Standard Philippine Rubber or SPR10 is a processed natural rubber turned into blocks. It is a semi-finished product used for further processing and applications of various industries. This grade of product may be used used on a wide range of applications including but limited to the following : Inner Tubes, conveyor belts, footwear, water proofing materials, hoses, tubes, and all types of automobile tyres.

In our town we can provide every month 60 tons of raw rubber (latex and rubber cup lumps) however, we are not capable collecting all of it and shipping the product since we lack finance or budget.
I would like to invite your company to establish a factory here for your rubber needs as
a partner. Helping your company to have a sustainable source and also helping my town.
Hope you find this offer as an opportunity.
Thank you.

Various ionic forms of styrene butadiene latex emulsifying asphalt modifier
Application field
Various ionic forms of styrene butadiene latex emulsifying asphalt modifier are mainly used in the adhesive layer of road engineering, sealing layer, modified dilute slurry sealing layer and micro-surface, bridge deck waterproof bonding layer, waterproof coating of building waterproof engineering, waterproof ointment and other aspects.
Product features
Various ionic forms of butadiene latex emulsifying asphalt modifier, is a stable emulsion synthesized by high polymer material under the condition of low temperature, it is developed according to the properties of modified emulsified asphalt. The temperature sensitivity of asphalt can be significantly improved by emulsion asphalt modified with butadiene latex, low temperature property, adhesion property, crack resistance and aging resistance can be improved.
Waterproof rubber spraying quick-setting latex can significantly improve the spraying quick-setting rubber asphalt waterproof coating after curing of heat resistance, bonding strength, low temperature flexibility, tensile properties and the puncture resistance after the coating film, It amends the coating after curing, such as its resistance to puncture and poor elastic recovery.
Special SBR styrene butadiene rubber asphalt modifier for waterproofing
New product introduction
In order to pushing the industry development, improving product quality, meeting with the demand of customers. HaiFang Rubber Technology developed XYF - ( item no. 095) styrene-butadiene rubber modifier in 2019.
It grafted based on the latex and in particles form. In order to guarantee the high content at the same time, compared with normal SBR products, it can be dissolved without using colloid mill and the dissolution time is shorter. As a new kind of environmental protection material. Its main advantages: Lower melting temperature, reducing production cost, greatly reducing the dust while feeding compared with normal SBR powder.
Product features
095 Waterproof SBR styrene butadiene rubber asphalt modifier is made by a certain amount of styrene in SBR styrene butadiene latex, initiated and catalyzed reaction, the formation of SBR rubber latex with a certain degree of interposition thermoplastic. The experimental results show that the high temperature properties, tensile properties, tensile strength, bonding strength and anti-aging properties of the materials can be improved obviously by adding it.
To meet different customers requirements, 095 modifier was upgraded to two different kinds of products: High and low-temperature property.
High temperature performance: Cohesion strength is higher than that of ordinary SBR modifier with strong peeling strength, the softening point is 4-6 higher than ordinary SBR modifier. Recommended for using in non- curing products.
Low temperature performance: It is better than the ordinary SBR modifier, low temperature index is 4 lower than the normal SBR modifier, and it has a better viscosity. Recommended using in type adhesive material.

Method of use
A certain proportion of styrene butadiene rubber powder should be mixed slowly into the emulsified bitumen at 140 C-150 C. Then raising the temperature to 185 C-195 C for stirring, until the styrene butadiene rubber powder is fully mixed evenly and swollen while stirring about one and a half hour and with no distinct particles.
