Capryllactam | Premium Nylon 8 Specialty Monomer | CAS 935-30-8

Overview

Capryllactam, also recognized scientifically as 8-Octanelactam or Azacyclononan-2-one, is a highly specialized 9-membered ring cyclic amide. As a premium long-chain homologue of caprolactam, it serves as the essential monomer for the ring-opening polymerization of Polyamide 8 (Nylon 8 / PA8). By further reducing the density of amide bonds along the polymer chain, Capryllactam yields a highly engineered plastic that features exceptionally low moisture absorption, outstanding chemical resistance, and unparalleled low-temperature flexibility.

Capryllactam | Nylon 8 Specialty Monomer
CAS: 935-30-8 High-Purity Synthesis Grade General Cargo (Non-DG)
Product Overview

Capryllactam, also recognized scientifically as 8-Octanelactam, is a highly specialized 9-membered ring cyclic amide. As a premium long-chain homologue of caprolactam, it serves as the essential monomer for the ring-opening polymerization of Polyamide 8 (Nylon 8 / PA8). By further reducing the density of amide bonds along the polymer chain, Capryllactam yields a highly engineered plastic that features exceptionally low moisture absorption, outstanding chemical resistance, and unparalleled low-temperature flexibility.

At Shandong Yinglang Chemical Co., Ltd., established in 2011, we supply bulk volumes of High-Purity Capryllactam (≥ 99.0%) to avant-garde polymer research institutes and elite specialty plastics compounders. Shipped seamlessly as Non-Dangerous Goods, our Capryllactam is packaged under strict moisture-barrier protocols, empowering your reactors to synthesize premium PA8 polymers for the most demanding extreme-environment applications.

Technical Specifications (COA)

For high-viscosity PA8 polymerization and demanding engineering extrusions, strict control of trace moisture is essential. Typical specifications:

Purity (Capryllactam) ≥ 99.0%
Moisture / Water ≤ 0.1%
Color (APHA, 50% solution) ≤ 30
Melting Point 70°C - 74°C
Key Applications
  • Nylon 8 (PA8) Polymerization: Synthesized into PA8 chips, which provide superior dimensional stability and low-temperature toughness compared to standard Nylon 6 and 66.
  • Extreme-Environment Extrusion: Extruded into highly flexible tubing and wire insulation specifically designed to resist cracking in sub-zero aerospace and arctic applications.
  • Specialty Elastomers: Copolymerized into advanced polyamide elastomers and hot-melt adhesives requiring enhanced flexibility.
  • Complex Intermediates: Utilized as a specialized cyclic building block in the organic synthesis of novel active ingredients.
❄️ Engineering Ultimate Sub-Zero Flexibility

While standard Nylon 6 is strong, it becomes brittle in sub-zero environments and swells when exposed to humidity. By upgrading your polymerization feedstock to Capryllactam, you introduce an 8-carbon backbone that significantly reduces the polymer's amide bond density. This translates directly to Polyamide 8 (PA8) — a specialty material that maintains exceptional flexibility and resists impact cracking at temperatures far below freezing, making it the uncompromising choice for deep-sea umbilicals, arctic pipelines, and aerospace wire coatings.

Strict Moisture-Barrier Packaging (Non-DG)

Because Capryllactam is hygroscopic, we utilize premium barrier packaging for secure global transit:

  • 25 KG UN-approved Fiber Drums with thick double-layered PE inner liners (Tightly sealed to ensure zero moisture ingress).
  • 25 KG Multi-wall Kraft paper bags with heavy-duty PE inner liners.

FAQ

Q1: What documents and certifications do you provide?

A Standard shipment includes COA (Certificate of Analysis) and MSDS (SDS). We also provide ISO 9001 certification and support third-party inspections like SGS or BV upon request.

Q2: Do you provide custom synthesis or formulation services?

A Yes. If you have specific purity requirements or a unique formulation, our R&D team can provide custom synthesis and adjust the stabilizers/inhibitors to meet your technical specifications.

Q3: What are your terms of payment?

A For Orders ≤ $1,000: 100% in advance.
For Orders > $1,000: 30% T/T in advance, and the balance before shipment or against the copy of B/L. Irrevocable L/C at sight is also acceptable for bulk orders.

Q4: How long is your price valid?

A Chemical prices fluctuate due to the changes in raw material costs and exchange rates. Please contact our sales team for the latest real-time quotation.

Q5: What packaging and shipping ports are available?

A We normally ship from Qingdao, Shanghai, or Ningbo.
Standard packaging includes 200kg Drums or 1000kg IBC Totes. We ensure strict safety compliance for both general and hazardous chemical cargoes.

Q6: It's my first time importing chemicals — can you help?

A Absolutely. Importing chemicals requires specific documentation. Our experienced logistics team will assist you with the entire process, including handling customs clearance documents and arranging the most suitable shipping method.
