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 Selection Workflow
1
Process & Requirement Definition
Map the unit operation and define the functional, purity, and regulatory requirements the chemical input must meet.
2
Chemistry & Grade Selection
Match the solvent, intermediate, acid or base, catalyst, or specialty additive to the process and downstream compatibility.
3
Trial & Specification
Validate performance at bench or pilot scale, and set the grade, treat rate, and packaging to match throughput and handling.
4
Quality & Supply Assurance
Lock the spec with a CoA and secure multi-origin sourcing for supply resilience and consistent lot quality.

消泡 / 抑泡
1274 (N-PROPANOL) · Class Low-surface-tension alcohol for transient foam knockdown where silicone carryover into the product is unacceptable

IPA (Isopropyl Alcohol)
CAS 67-63-0
溶媒
General-purpose cleaning solvent
1219 (ISOPROPANOL) · Class Structural isomer of the already-listed N-Propanol (both C3H7OH); near-identical low surface tension (~21.7 mN/m) and water-miscibility give the same Marangoni-suppression / foam-lamellae destabilization mechanism and the same silicone-free, no-PDMS-residue transient-knockdown value. A genuine direct analog to the incumbent, not a role-only look-alike.
融点:-88 °C 沸点:82 °C at 760 mmHg 密度:0.785 at 20 °C

Ethanol
CAS 64-17-5
Water-miscible low-surface-tension (~22 mN/m) short-chain alcohol and a well-established aqueous/protein foam breaker via the same film-destabilization mechanism. Slightly less hydrophobic than the propanols but same class and same silicone-free niche; its higher volatility strengthens the no-residue story for contamination-sensitive process lines. Genuinely serves this exact use-case.
