CNSL & Sustainability
Built for Predictable Performance.
Palmer is built on one chemistry: cashew nutshell liquid (CNSL).
CNSL is a renewable, non-petroleum feedstock with a unique molecular structure that enables high thermal stability, friction control, durability, and performance consistency across performance-critical applications.
At Palmer, CNSL is not a marketing claim, IT IS OUR TECHNOLOGY PLATFORM.
We engineer every formulation to deliver predictable, repeatable performance—from initial qualification through full-scale production—so our customers can operate with confidence.
What Is CNSL?
Cashew nutshell liquid (CNSL) is a naturally occurring material found within the honeycomb structure of the cashew shell. It’s an abundant raw material that does not compete with its food crop.
Through controlled processing, particle engineering, and disciplined formulation, CNSL becomes a versatile, high-performance chemistry capable of replacing petroleum-derived and phenol-based systems in demanding environments.
WHY CNSL?
Palmer’s edge in expertise and application
By engineering all materials from a single renewable feedstock, we:
- Maintain consistent formulations across applications and programs
- Replace fossil carbon with renewable carbon
- Reduce variability during reformulation and scale-up
- Accelerate validation and qualification cycles while minimizing risk
- Support a circular economy
- Replace petro-driven phenols and surfactants
This disciplined platform approach allows Palmer to innovate responsibly.
Sustainable without sacrificing performance
Many sustainability initiatives fail because they force manufacturers to choose between
environmental goals and performance certainty.
Palmer eliminates the trade-off.
Our CNSL-Based Materials Are Engineered To:
- MATCH Or Exceed Petrochemical AND PHENOL-BASED Alternatives
- Withstand Demanding Thermal, Frictional, And Mechanical Stress
- Support Long Product Lifecycles
- ADAPT TO Evolving Regulatory Requirements
At Palmer, sustainability is engineered at the molecular level: integrated into the chemistry, validated through structured development, and delivered with the consistency our customers depend on.
application-driven sustainability
Palmer’s CNSL-based materials support:
- Friction and braking systems
- Industrial and power transmission
- Coatings, epoxies, and composite systems
- Specialty and custom formulations
Across every application, sustainability is achieved through engineering discipline, transforming agricultural waste into high-performance materials.
REPLACING FOSSIL CARBON WITH RENEWABLE CARBON.
sustainability you can validate
Palmer’s approach is grounded in:
- Renewable feedstock origin
- Measurable performance data
- Lifecycle awareness
- Documented validation processes
- Stage-Gate development discipline
This is sustainability THAT engineers, quality teams, and OEM leaders can stand behind.
