Rubber — Process Challenge

ゴムコンパウンド用可塑剤・軟化剤

ゴムコンパウンドの軟化と加工性向上のため、エクステンダーオイルおよび可塑剤の選定。ナフテン系・パラフィン系石油系エクステンダーオイルを中心に、軟化・流動性付与を担う可塑剤タイプの軟化剤も併せてカバーするが、後者はバルクの石油系エクステンダーオイルではない点に留意されたい

ソリューションアプローチ

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Formulation Workflow
1
Polymer & Process Definition
Identify the resin and process (extrusion, molding, film) and the targets — thermal stability, clarity, flame retardance, slip, or color.
2
Additive Selection
Match stabilizers, antioxidants, plasticizers, lubricants, flame retardants, or masterbatch carriers to the polymer and processing temperatures.
3
Compounding Trial
Confirm loading and dispersion on a compounding or molding trial, checking processability, mechanicals, and aesthetics against the control.
4
Validation & Scale-Up
Verify long-term performance (heat aging, migration, weathering) and lock the formulation, packaging, and lot specs for production.
Recommended Chemistries (5)
Epoxidized Soybean (ESBO)
CAS 8013-07-8
特殊添加剤
エモリエント
Bio-based plasticizer/co-stabilizer genuinely used in elastomer compounds: it softens the compound, eases processing, and scavenges acid; the closest real softening match to a process oil in the spine

Dioctyl Terephthalate (DOTP)
CAS 6422-86-2
特殊添加剤
可塑化
Non-phthalate (ortho-free) plasticizer that inserts between chains to lower compound hardness/viscosity for softening — a plasticizer-type softener, not a petroleum extender oil
Physical Description: Pellets or crystals or liquid   沸点:383 °C   融点:-48 °C

詳細情報
Diisononyl Phthalate (DINP)
CAS 28553-12-0
特殊添加剤
潤滑
General-purpose plasticizer that lowers compound viscosity/hardness and eases processing; a softening adjunct rather than a bulk extender oil
Physical Description: Di-isononyl phthalate is an oily colorless liqu…   Appearance: Colorless liquid   沸点:78 °C at 760 mmHg

Paraffin Wax
CAS 8002-74-2
特殊添加剤
界面活性
Legitimate rubber processing/lubricating wax and physical antiozonant carrier that aids flow and surface bloom in rubber compounds

詳細情報
Dioctyl Phthalate
CAS 117-81-7
Canonical general-purpose ester plasticizer for polar elastomers (NBR/CR), which are incompatible with petroleum process oils and use DOP in their place as the softener/processing aid — exactly the softening/flow role the page covers; direct parallel to the already-listed DINP phthalate.
