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 (4)
UV-328 Benzotriazole UV Absorber (Tinuvin 328 Type)
CAS 25973-55-1
特殊添加剤
Organic UV absorber
Hydroxyphenyl-benzotriazole UV absorber; absorbs 300-380 nm UV and dissipates it as heat to protect the polymer from chain scission
Physical Description: Dry powder, pellets or crystals, or solid Appearance: White to yellow powder or crystals Solubility: In water, log -1.37

Benzophenone-3
CAS 131-57-7
特殊添加剤
UVカット
Benzophenone UV absorber; harmlessly dissipates absorbed UV energy as a low-cost broad screen
融点:66 °C 沸点:150–160 °C at 5 mmHg 密度:1.32 at 25 °C

Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate (HALS, Tinuvin 770 type)
CAS 52829-07-9
Hindered-amine light stabilizer; the nitroxyl/NO regenerative cycle scavenges chain-propagating free radicals to interrupt photo-oxidation (not a UV absorber) (source on demand)
