Start with Enoch
PVC 100kg + calcium 200kg + additives. This is the stronger rigid-core starting point.
Flooring knowledge
Start with the formula.
Ignore the sample first.
Most buyers are shown colour, softness, and price first. The real decision is simpler: which route has more PVC, less filler pressure, and fewer chemical questions.
Fast verdict
Screen ordinary SPC
PVC 100kg + calcium 330-450kg + additives. Rigid route, but often pushed cheap with too much filler.
Question vinyl first
PVC 100kg + calcium 350-500kg + liquid plasticizer 25-35kg + additives. Softness comes with harder chemical questions.
Route comparison
Three routes. One default answer.
These are different material routes, not cosmetic variations of one board.
Vinyl flooring
Soft route. Harder questions.
Formula
PVC 100kg + calcium 350-500kg + liquid plasticizer 25-35kg + additives
When to use
Only after the buyer accepts the plasticizer route and checks the compliance file.
Main risk
More temperature sensitivity and more chemical scrutiny.
Verdict
Do not default to this route.
Ordinary SPC
Rigid route. Often costed down.
Formula
PVC 100kg + calcium 330-450kg + additives
When to use
Budget jobs only after asking about calcium level and lock strength.
Main risk
Extra calcium usually means more brittleness and weaker locking.
Verdict
Low price is a warning sign.
Enoch flooring
Rigid route with stronger material logic.
Formula
PVC 100kg + calcium 200kg + additives
When to use
Homes and projects where stability, toughness, and lower filler loading matter.
Main risk
Real material cost is higher, so it will not be the cheapest quote.
Verdict
Start here when quality matters.
Material basics
Four materials explain most boards.
One gives real strength. One is often used to cut cost. One creates the soft route. One only helps stability.
PVC
PVC is the real body of the board.
What it does
It binds the board together. More PVC usually means more real core material and better toughness.
Too much
It raises cost. Stronger boards are rarely the cheapest boards.
Too little
The board has to lean on filler instead, and the core usually gets weaker.
Buyer rule
More PVC usually means a stronger board.
Calcium powder
Calcium can help, but it is also where cost-cutting usually starts.
What it does
In a controlled range it helps cost balance and movement control.
Too much
The board usually gets more brittle, weaker at the click-lock, and easier to break.
Too little
This is rarely the market problem. Too much calcium is the real risk.
Buyer rule
More calcium usually means more cost-down pressure.
Plasticizer
Plasticizer is what makes vinyl soft, and that is where the hardest questions begin.
What it does
It creates the soft feel many buyers notice first.
Too much
Usually means more softness, more temperature sensitivity, and more health scrutiny.
Too little
A soft vinyl route would not behave like vinyl in the first place.
Buyer rule
Softness is not free. It comes with more questions.
Fiberglass mesh
Fiberglass mesh helps stability. It does not turn a weak board into a strong one.
What it does
It helps the board stay flatter and supports dimensional stability.
Too much
More mesh does not fix a weak core formula.
Too little
The board has less help controlling movement.
Buyer rule
Treat it as a support layer, not the real source of strength.
Caution
The soft route carries the hardest questions.
Adults
Hormone and fertility questions do not belong in a default flooring route.
Children
Floor-level dust matters more in children’s rooms and family homes.
Pets
Pets stay low to the floor and take in more floor dust over time.
Buyer rule: if softness is the sales pitch, ask what chemical route created it and ask for proof.
How to choose
Decide first.
Then question the seller.
Choose Enoch first
when you want a stronger rigid-core start: higher PVC, lower calcium, and no liquid-plasticizer story.
Screen ordinary SPC hard
when the offer is cheap. Ask calcium level, brittleness risk, lock strength, and whether the core is being costed down.
Do not default to vinyl
when the room is for children, pets, long-term living, or anyone who wants fewer chemical questions and better rigid stability.
Four questions
Ask these before price matters.
How much PVC is actually inside the board?
How much calcium powder was added?
Is the route phthalate-free, and what plasticizer system is being used?
What is fiberglass mesh doing here, and what gives the board its real strength?
FAQ
Short answers only.
What is the fastest way to tell vinyl, ordinary SPC, and Enoch apart?
Start with the formula. Vinyl depends on liquid plasticizer. Ordinary SPC is rigid but often costed down with more calcium. Enoch keeps PVC higher and calcium lower for a stronger rigid-core route.
Why does too much calcium usually weaken SPC flooring?
Because calcium is filler, not the main binding material. In a controlled range it can help, but once it is pushed too high, the board usually gets more brittle and weaker at the click-lock.
Why is plasticizer the hardest question in vinyl flooring?
Because plasticizer is what makes vinyl soft. That softness comes from a different chemical route, so buyers should ask whether the route is phthalate-free, what system is used, and whether proof documents exist.
Next step
Know the route first.
Then compare product and price.
Once the route is clear, weak boards lose their main hiding places: low price, colour, and soft sample feel.
