Buyer-friendly explanations of technical terms, logistics terms, and document labels used across the Borvanta site.
AFS
A foundry sand grain-fineness classification used to describe sand texture.
AFS helps buyers judge whether a sand grade fits mold-making quality, finish, and process stability.
Resin content
The binder percentage in a prepared foundry sand mix.
Resin content affects mold strength, handling behavior, and foundry process fit.
K-value
A PVC resin parameter used to indicate molecular-weight-related processing behavior.
Buyers use K-value to narrow down whether a PVC resin grade fits pipes, profiles, sheets, or compounding work.
Suspension PVC resin
A raw PVC resin grade produced for downstream industrial processing.
It tells buyers they are looking at a raw resin input, not a finished PVC product or compound.
Al₂SiO₅
An aluminosilicate refractory composition associated with minerals such as kyanite and sillimanite.
It helps refractory buyers identify the mineral family and compare use in high-temperature applications.
Kyanite-sillimanite concentrate
A refractory mineral raw material used in high-temperature mixes and furnace-related applications.
It distinguishes a refractory input material from a finished refractory product.
EXW
Ex Works. The buyer arranges pickup from the agreed warehouse or loading point.
It changes who controls pickup, loading coordination, and the first transport leg.
FCA
Free Carrier. The seller hands goods to the carrier at an agreed place.
It clarifies the transfer point for responsibility during transport planning.
CPT
Carriage Paid To. The seller pays for the main transport to the named destination.
It affects freight cost allocation and delivery planning during quoting.
DAP
Delivered at Place. The seller arranges delivery to the named destination, ready for unloading.
It matters when buyers need clearer delivered-price planning instead of pickup terms.
COA
Certificate of Analysis. A batch-linked document showing relevant technical results.
Buyers use COAs to check whether a supplied lot matches the agreed batch-level data where applicable.
TDS
Technical Data Sheet. A summary of typical product specifications and performance context.
It helps buyers screen product fit before deeper quote or batch review.
MSDS
Material Safety Data Sheet. Safety and handling information for storage, transport, and use.
It is relevant when buyers need safety handling context before transport or internal approval.
CMR
A standard road transport document used in commercial shipment handling.
It matters when buyers need clarity on transport paperwork for road freight execution.
MOQ
Minimum Order Quantity.
MOQ tells buyers the smallest commercially workable order structure shown on the page.
RFQ
Request for Quote. The buyer sends product, quantity, packaging, destination, and timeline details for review.
RFQ is where documentation scope, logistics terms, and commercial fit are clarified before order work starts.
Use the Borvanta resources section for short explainers on foundry sand terms, PVC resin terminology, refractory material context, and RFQ workflow.
