In fact, the rubber formulation technology is a kind of selection and use ofmaterials science and art. Rubber formulations of general purpose has three: first is to make the rubber product with practical things; second is to cooperate with the existing processing equipment for processing operation well; finally is tofurnish the lowest cost possible to meet customer demand level.

In other words, rubber formula design the need to consider the three elementsas ingredients of, processing and cost, and makes the three to obtain a properbalance point, which is the main work of formulation design. Additives commonly used in the formula can be classified into ten major components: copyrightrubber information network

• rubber or elastomer (elastomers):

Rubber formula design the first step is the most important step is to choose the rubber base material or rubber materials. Rubber is one of the engineering material, regardless of its composition and why, with some common basiccharacteristics. All rubber has elasticity, flexibility, toughness, is not easy to bepermeable and air permeable properties. In addition to these common characteristics, each kind of rubber with different composition, each having its own properties. • vulcanizing agents (Vulcanizing agents):

Add to add sulfur agent is the ingredients to produce chemical reaction andproduce bridge between the rubber molecules (cross linking) phenomenon andchange the rubber properties. The chemical bridging the rubber blendingthermoplastic made of soft, sticky body into thermoset and the influence of temperature, the less. So far, the sulfur is still the most widely used vulcanizingagent. Other sulfurizing agent (sulfur donor) such as TMTD two vulcanizationthiuram of (TUEX) is also sometimes used as all or partial substitution formula ofelement sulfur in sulfur or sulfur free and sulfur system, so that the product canimprove its heat resistance. The second most important formulation designerworking for ingredients plus sulfur system, select Add sulfur agent and promoter of the.

• vulcanizing accelerator (Accelerators): This article from the rubber information network

The sulfur accelerant vulcanization rate and shorten the ingredients of sulfur addition time.

• activator (Activators) and delay agent (Retarders):

Activating agent is used to help the accelerator to increase its activity andefficiency, the most commonly used activation agent zinc oxide, stearic acid, lead oxide, magnesium oxide and amine (H).

• antioxidant (Antidegradants):

The antioxidant can delay the rubber product due to oxygen, ozone, heat,impact and bending motion metal catalysis and degradation. Therefore theantioxidant on ingredients can enhance the products of aging and prolong itsservice life.

• processing aids (Processing AIDS):

Processing aids that means help ingredients for processing operations, such asmixing, calendering, extrusion and molding etc.. • filler (Fillers): please remember our website: Rubber Plantation

The filler can enhance the ingredients of help processing, or reduce the cost.Reinforcing filler can increase product hardness, tensile strength, tensilestrength (modulus), tear strength and abrasion resistance. Mineral materialscommonly used carbon smoke or fine particles.

• plasticity (Plasticizer), softening agent and tackifier (Tackfier): plasticity,softening agent and thickener is used to help rubber mixing, changing itsviscosity, viscosity enhancement ingredients, improve products in the low temperature flexibility, or partially replacing glue without too much influence onproperties. Generally speaking, these types of additives as a processing aid orextension agent. Rubber information network, xiangjiaoyuan.com

• pigment (Color Pigment): Rubber information network, xiangjiaoyuan.com

Pigment is used for blending non smoke class in order to provide specific color.The commonly used pigments can be divided into organic and inorganic.Inorganic iron oxide, chromium oxide, titanium dioxide (titanium dioxide), CDs,CdSe, antimony, mercury, lead powder (lithopone) and navy blue etc..Http://www.xiangjiaoyuan.com

It is much more expensive than organic pigments inorganic pigment. But its useeffect is good, color bright and proportion is very low. And the color organic pigment changes more than inorganic pigment. However, most of the organic pigment of steam, light, acid or alkali are unstable, and they sometimes wander to the product surface.

Materials for special purpose is not often in the water most of the ingredientssuch as foaming agent, flavoring agent, adhesive agent, flame retardant, anti mildew agent and UV absorbent is. Please remember our website: Rubber Plantation

Formulation design program: This article from the rubber information network

Almost all the new formula from the existing formula is modified into. At present,has been appointed to a few people try to design a new formula, because in practice is not required. In order to make the formula, the formula design staff should try to use all kinds of internal or external information technology there,then according to the required to arrange, analysis, and the use of personalimagination and creativity of the design formula. Each step can be used as a reference for design of the following formula.

• development of existing test data of similar ingredients.

The technical data, various kinds of related reference materials.

• set the initial formula.

• try to test the small sample properties can meet the target. Please remember our website: Rubber Plantation
